Basic Graphs that Every Algebra Student Should Know!!

[mrassassin209]

thank you this helped alot

[Jvk156]

@thedude9396 And... if anything that i said offended you i'm really sorry it's my fault.

[Jvk156]

@thedude9396 oh... well in that case it's cool i thought you called me stupid in a sarcastic way but since you didn't it's okay, we cool.

[Jvk156]

@thedude9396 i listen... if the teacher's hot i get A's at any subject.. but this probably might be the first time ever i have learnt something without being sexually attracted to a teacher who i want to impress by getting good grades at the subject she is teaching... besides i just said that as a joke cause it looked like that but anyhoo this guys is really good at teaching these stuff i understand 100% on what he's trying to say.

[missxick]

if i watch all 1,245 vid, would i master math

[khmerkidlove]

Lol, thanks alot, my math homework almost done :D

[Jvk156]

at 1:42 you know why you call maths the devils subject...

[Anitaalwinarock]

Good math teaching.

[tralynTM]

Your handwriting is beautiful x.x

[ascrysis3]

OH NO My sats >< oh well i can always take it next year

[cobinigers]

thanks for the help, i am just about to test out of algebra A and go straight in to algebra B from pre-algebra and i need all of the help that i can get!!! you did a very good job on helping me understand the piecewise function better.

[bumussab2008]

Thanks for the great vidieo!

[nathank16]

shouldn't the last graph for a^x be for less than 1 BUT GREATER THAN ZERO???

[exscape]

@nathank16 That's exactly what he has. 0<a<1 = "a is greater than zero but less than one".

[pitadinic]

man can i put u in my pencil case and bring u to my exam?? :P

[Dreamer25Yup]

I wish you were my math teacher!

[mohd1716]

thank you so much .... Patrick... your videos are amazing ...you are fantastic man thank you ...

[mohd1716]

thank you so much .... Patrick... your videos are amazing ...you are fantastic man thank you ...

[nikga777]

it takes a man to post math lessons for kids in need...mr. Patrick, I love you

[HarrisAmir]

u did the y wrong way around.

love the tutorial.... subed

[Flextext1]

mkay!

[XpianoxboyX]

why is math so confusing.

[patrickJMT]

@XpianoxboyX not everything in life is simple

[jannybugalicious]

@XpianoxboyX It's all designed to condition your brain, logically. :)

[XpianoxboyX]

@jannybugalicious apparently

[TheInquisitiveBeing]

when drawing y=sq root of x, why didn't you draw the graph below the x axis as well as you did above it? sorry for bad english, hope you understand the question

[patrickJMT]

@TheInquisitiveBeing because the square root of a number is by definition a positive number.

by far, one of the most common mistakes is for people to say something like:

sqrt ( 9 ) is 3 and - 3 ; however sqrt ( 9) is 3 ONLY!

[patrickJMT]

@patrickJMT that is, the square root is positive if you start with a positive! it could of course be zero as well if you take sqrt ( 0 )

[TheInquisitiveBeing]

@patrickJMT ok tnx

[Phoenix941000]

@patrickJMT wrong, -3^2 is 9, AND 3^2 is 9, so, square root of 9 can be 3 or -3.

[patrickJMT]

@Phoenix941000 zzzzzzzzzzzzzzzzzz

[ryan2929]

@Phoenix941000 LOL

[WSWarthog]

@Phoenix941000

It's a matter of domain.

[GMATWalkthrough]

What did you use to record the video?

[jason22288]

thx "DUDE" teacher watever!?!??!?!?!!

[xfarahkhanx]

that was confusing!!!

[Jontzgu]

Isn't the parabla..(i dont knowthe word in English ) function like this to be exact y=ax^2+bx+c. Nice tut, very clear!

[kyla100896]

4x1=

[lenaax]

I wish you were my teacher.

[jeffreyyiu19]

very helpful ! but i think the modulus part is kinda wrong. i get what u mean by V shape graph but if y = l x l it should be a horizontal line :D

[RockNRollRanter]

Thank you, sir! I needed a visual to help me memorize this stuff--just started it this week...Thank you, thank you, THANK YOU!

[SierraSuicidalScream]

oh my godddd. you teach better than my math teacher lol thts sad in her case

[ravi00090]

Patrick, I got a problem with graphs in the sense that I get totally dumbfounded when they make a curve for a graph of x^2. or they make half curve for graph of root x. My basics are weak, yeah. I wanna know basically why is it like a curve for x^2? and why half a curve for root of x? I really desperately need help Sir. Can you help me with that?

[Chafezi]

Hey man,

Just look at what the y values become at any value of x. For y=x^2, y is always positive, and is shown in the graph.

For the y= sqrt x, notice that there are no negative x values shown, since the sqrt of a negative value does not exist, leaving the curve only in the first quadrant.

[Shakespeare1612]

@ravi00090 No magic here. Each time you plug an X, you get out a Y. You plot each x along the x axis, and the y values along the y axis. Each time you will get a dot, but if you run it infinite times then all of the dots will run together into one smooth line. You get a curve for x^2 because squaring a number makes the number get big very quickly 2*2 = 4. 3 * 3 = 9. 4 * 4 = 16.. 5 * 5 = 25. I am only changing the x by 1 but my answers get HUGE. These dots, when plotted, flow into a curve.

[ravi00090]

@Shakespeare1612 Thank you for that buddy, I got it now. So I guess there must be similar logic about other graphs too then?

[hobbschoice]

did you make this on your cell phone?

[patrickJMT]

yes

[GrappyFlappy]

@hobbschoice How about you thank the guy for saving our asses in math class? Don't be a hater

[ohhhleslie]

Damnnn! I wish you were my professor, id so kick mine out cuz he talks to the board lol. Where's the fking genie when you need one!!

[batmanforever32]

fk i get so fk lost!.....lol

[HowAboutSomeTruth1]

You'd need to build a time-machine for that. Gona need some advanced maths to build one...

[Darkhole1444]

im confused!!

[m33lad]

The sound is horrible!! OH My God!!

[tdog661]

ur awesome

[emoemoemo13666]

wait where'she getting ( 1:35 ) those numbers?he just liike pulls them out and i can't really understand wat he says after" if you plug 1 in for X you'll get -1"

[MrEinsteinz]

He's saying if you plug in -1 for X, you'd get y = (-1)^2 and a negative number to the power of two becomes a positive number, 1. The y-coordinate would be y = 1 because you were solving for Y in the first place... which you got 1. (-1,1). X was -1, Y is 1. Left side negative numbers, right side positive numbers on the x-axis...

Y = (1)^2 = 1. 1 x 1= 1. Y=1. (1,1).

[rhesusthemonkey]

you draw the coordinate system incorreclty

[patrickJMT]

okie dokie

[sakurabaka]

I wish I had an ipod just so I could download your videos.

[Yu2Kal]

Maybe you should have done sin, cos and tan graphs, but it was still good!

[patrickJMT]

maybe i will! : )

[Yu2Kal]

yay u replied, i wud like to take this opportunity to tell u that ur the best teacher ever, the proof is ur vids! great job =D

[LKJPDUR]

LOVE THis. . (regardless of the Buzz) ... Vice is Great.

[patrickJMT]

thanks : )

[mzbanks4life]

THANKS

[ofwiteblodcels]

thanks alot

[randomchiful]

You give me the idea, and sacalante grow up from user to guru (ruler), just for fun. Kind Regards.

[Fucenpy]

your videos are super helpful but, the sound on this one almost blew my speakers...  again, Super helpful!

[khasruabid]

it is very good

[sacalante]

I from sto 1 command so you must be from dos, we can get fun with distro, but please share and remember we are just human beings, get fun math and i hope my best video i have. Kind Regards.

[sacalante]

Sorry i was wrong, we are just human beings, but better and faster than a 10 ring web server, you are to best. Kind Regards..

[Bauter]

im 22 and needed a refresher because im finally going back to school... thanks man..

[EditYourVideos]

Wow you're good at math. I wonder... try to calculate (using a calculator is cheating) how many trees you've wasted so far?

[proatmetazine30906]

Hey patrick,

If I just substitute numbers(x,y)

it will just graph naturally and we dont have to remember these graphs right?

we just connect the dots in a curving manner right?just make enough points for harder functions then connect them.

[patrickJMT]

yep, you can always just plot points to get the graph!

[patrickJMT]

sure it is

[callienumberfan1]

im haven tobblie with math can you help?

[buckeyelaker]

Do you know how to skecth a graph

x-8+2 is < 8?

[Harholt]

Its easy to skecth this but it will not be a graph of a function.

Your inequality is the same as x<14.

Put a book or something to the right of the x-axis were x equals 14. Then scetch the rest of your sheet,

[buckeyelaker]

Okay. Thankyou.

[Shakespeare1612]

@buckeyelaker I Do. This is the graph of an innequality. It will have an entire shaded region that represents all of the possible correct answers, first solve it.

x -8 + 2 < 8 combine -8 and 2

x -6 < 8 add 6 to both sides.

x < 14 6 + 8 = 14.

Now put a book or something to the right of the x axis where x equals 14, and scratch the rest of the graph. Put a straigh dashed line exactly at x = 14, from top to bottom.

[POBOX180]

thanksss

[rumma85]

From North of the 49th Parallel. Thank You ...Thank You. Fantastic job. Patrick for President.

[patrickJMT]

look out obama and mccain! : )

[montannapaint]

thanks man that was very helpful because my teacher cant teach

[whaizthah]

same lol thnkxs man

[FRANRIOS]

This guy is awesome!!!

[Tehhunter1]

again, surprised by how straight ur lines are :P thanks for the info, that helped me since i missed the class they taught that in ^^

[xoxoChristiina]

Oh man thank you! I feel asleep in algebra 2 hon. class today when my teacher was giving a lesson on parent graphs/transformations... This really clarified it for me! Bravo!

[patrickJMT]

stay awake in class! : )

or just sleep and watch my videos!

i am your teacher now!

i will assign the following problems from pg 80: 1-100, all of them!

[mbond65]

helps to clear up sooo much for me. thank you

[patrickJMT]

glad to help! they are rough, but usually a general sketch is still very useful!

[afgsabrina07]

thank you

[hedgehoggirl0625]

oh my gosh, thnk yu so much! :]

i hav this huge AP placement math test tomarrow. & i need to review. thanks again!

[DigitalCynicismArt]

This is very informative by your methods of Y= 1/x and 1/2x. I failed Algebra in the first semester, very difficult for me, but you clarify it better than my teacher does. Algorithms will help me validate an occupation with Graphic design.

[beckyp4win]

thank you, this is exactly what i needed to see.

[libardogonzalezalvar]

thank you very much. please keep posting such nice videos like this

thank you
