SAT Math Lesson 9 - Functions & Graphs! p1/4

[bleach123321]

u look like a character from harry ploper!

[MrHasnodong]

what score did u get on ur math?

[purpleleach1]

@MrHasnodong He got an 800 on the SAT math.

[onfire916]

Idk if this was said but to me that made no sense. So how about we use common sense and just multiply the 24 by 2 and add that to 0.... When you have like 20 minutes to do 20 problems wouldn't a quicker way be recommended???

[ilikejdmtlk]

are you a teacher?

[19912010ahcWoodburn]

oh yeah your good looking haha XD

Thank you!! this really help I got a test today at 3pm >:) so am ready to kill it >:) haha

[xEquals3x]

Just had dinner? 7:48 LOLOL

[101altair]

can this also work? since 1x is 24, 2x would be 48, and 0x would be 0, so a+b would be 48+0 which equals 48, the answer, would you reccomend this technique?

[purpleleach1]

@101altair That would work here but more most of these it wouldn't. It only works here because a does happen to be equal to 0 while other times it may not.

[xoxo24811]

thanks so much!! you're awesome :D

[SpiralxWarmth]

Ah, I notice my friend commented on this with my account. Commenting twice wasn't my intention.

[SpiralxWarmth]

Lol. Mate, I'll pass on the fact that ye were sort of geeky at the beginning, your teaching skills are High Quality. Keep up the good work, i sort of get this more now. Functions and Linear stuffs are one of my many Mathematics weak spots. @bananappletree; i got 1420 on my Pre-Sats <3 and I didn't even study <3<3<3

[SpiralxWarmth]

even though yer sort of dorky, thx for the less, teach! <3 \../

[Deathstars6]

Your good.....I like you! I'm doing my leaving cert tomorrow and you've helped. What the hell is SATs!?!

[PurpleSkittles23]

You're better than my algebra teacher (honestly, no offense to my algebra teacher)

SAT's in four days! I'm nervous, but this video helps :)

[TheHashami]

u're chinese???

[Temporaryaccount2]

a really easy way to do this question would be to assume that f(x)=24x therefore f(1)=24 f(0)=0 f(2)=48 thus a+b=0+48=48

[kyle9003]

@Temporaryaccount2 thats what i thought when i read the problem

[bananappletree]

thanks! these vids are a lifesaver i'm hoping to bring my score up to a 1300 and i havn't been in school for 3 years retaking it to get into a good college.

[MiTeach]

Cool, good luck!!!

[spamion]

well.... that really.....nvm

[yerovi86]

how did u get the values for x? im talking about 0,1,2 how do u get those?

[brainyflix]

I got them from the chart

[31rS3RP3N7]

asians are good at math.

yeah.

[yokamotoh]

love this guy aye

[BlackedWingedAngels]

wasup

[yougoddamnBITCH]

take this off. math is for whores

[misslolaxx]

omg this helped so much! im from the uk and i've never seen anything like f(x) in an equation or anything, so when i saw it in the practice tests, i was really confused, but i get it now, thanks =D

[Weeeeee55343]

This video really helped; before, I would definitely thought that the answer was e)

[aafaking]

this is the sneakiest question ive seen so far

[goflyers17]

omg you guys are such geeks!

[MiTeach]

dont playa hate! appreciate!

[KeylaKeyla]

hahaaha actually a geek is a carnival performer who does acts that consists of biting off the heads of chicken...

In no way are we geeks,,,

I'd prefer the term overly intellectual people : ]

[omkar2694]

Thank for the video , We need people like you .I am i grade9 rite now but i still understood some off the part. So thanks man keep making these videos

[komilkh]

there is another way of solving this problem. very easy one.

Since this is a line and we have its coordinates as (0, a), (1,24), (2, b).

24=(a+b)/2 because of the second coordinate is the midpoint of a segment with end points (0,a) and (2,b).

[nidiskt]

your 2's look like A's so it keeps confusing me. other than that thanks.

[MiTeach]

haha you left???  >:D jk. kwl! welcome back!

[bargior]

back again for daily lessons, I am hooked
