Understanding Functions Pt 3

[Danster82]

so functions are used when calculating variables within equations?

[frindgedcardigan]

thanks for the help, you should do longer vids though! :)

[mameddeman]

If f(4) = 0 and f(6) = 6, which of the following could represent f(x)?

send me a message with explanation pliz..

[andrewtrucker]

too fast when you say pie in pt one looks like you wrote pe and your confusing me with all these things better to just use banana i think.this pt 3 was way fast for me. Understan i failed this stuff in college and am trying to get it down now so i can feel like i am not stupid.most i got. butthe formula is explained enogh for me. i can understand you put those variables and letter in but is it to solve for g?

[Dheart8D]

Do u have inverse functions ? :O

i am asian yet i fail at math starting at geometry . ]: FAIL .

[shanghaiyue08]

ahhhhh thank you so much. Math is pretty much my enemy, but you've helped loads.

[sam4sam5]

great help, thanks

[polarsnake]

Sir you need to post some on inverse functions.

[lightsoutnow2008]

dude i got lost half way. can you plz explain on how you got the g involved and so on. thank you

[doommic]

i need inverse function..:(

[MaRmAn1337]

Seriously, is this hard for you? I mean expecially US citizens aged like 15-25 since they are the majority who post questions under these videos.

[Owyn999]

Poor teaching, memory gaps, and interest later in life are but a few reasons why people find these videos extremely useful. If you never properly understood Maths you wouldn't learn it by osmosis later in life.

im 12 almost 13 i understand this

[NiEcY2luv]

I really appreciate the math in 60seconds, because you don't have to take in more than you can chew, especially if math isn't your favorite subject. However I still can't grasp this type of function f+g, for f(x)-3x-6 adn g(x)=4x + 2 any help will do because I think I'm a lil confused. I got (9, 5)

gcsemathstutor . com this website helps shit load

[jenjensforpresident]

yeah this is pretty helpful stuff, thanks!

[musicismylanguage]

ok that comment sounded retarded , i mean u actually make it understandable

[musicismylanguage]

you are soo good , you actully it actually understandable

[farmer759]

man im in gr 9 and i dont really understand this...i think im going to research some more math like this.

[jeweladdiction]

What if the range of g is disjoint from the domain of f?

[zozikas]

Well its not hard , but your are good helper for those who sleep  at school :)

[ipunkbali]

yeah... please more !!!

[machta]

please can you explain shapes and measure and trig im so rubbish at it your posts are amazing by the way

[paxcoder]

Agreed. I always forget trig. I can practice it, and know how to solve it, but I don't understand it anymore.

[Shmuelthinker]

Can you do more complicated functions? the one involving divisions? thank you. ~Samuel
