It's right here ↴ (are you going blind? Bet your mom told you that might happen )

Find f(g(x)) When
f(x) = 3x - 21
and
g(x) = x^2 + 3

LOL you are supposed to put them together to find out what f (of) g is and then g (of) f is..

AKA a bunch of useless crap that you will never use in your lifetime!!

If you don't fight it it becomes your friend. The reason you struggle in learning it is because you fight learning it instead of thinking why am I doing this the whole time concentrate on doing it.

Don't post physics in a math thread.

i thought you find f(g(x)) so you put the g(x) into the X portion of the f(x). I think..

 

[Big Bully]

Isn't that physics Anty?

 

[logan9967]

yes that is.

Exactly.. and then you switch it and find g(f(x)) and then f(f(x))...

 

[Big Bully]

yes that is.

Thats what I thought.. I learned it in one of my classes.. I just couldn't remember which one..

TOO MUCH SCHOOL!:er:

Only when the problem requires it... It does make physics problems a lot easier once you understand that kind of stuff.

 

[monkeykoder]

That WAS meant as a joke...

 

[Big Bully]

Oh no.. Wouldnt' do that... Not over a simple problem.. I was just making sure my head was on straight.. lmao
