Question

MEDAL TO WHOEVER ANSWERS THIS QUICKLY!

Let f(x) = 2x,
g(x) = x^2 + 2,
and h(x) = -4x + 3.
Find the composite function
(f o g)

Answer 1

its all one question

Answer 2

your supposed to find (f o g)

Answer 3

0.0 what.

Answer 4

lol idk

Answer 5

weird...

Answer 6

i don't get what its asking

Answer 7

For fog... I almost have it figured out..

Answer 8

your supposed to find the composite function of (f times g) which is why i put (f o g)

Answer 9

and its all one question! not three!

Answer 10

@walking_stick you helped me yesterday can you help me today?

Answer 11

your confusing matters.

f (composed of) g, is not the same operation as: f (times) g

f o g is read: f (composed of) g

f*g is read as: f (times) g

Answer 12

well thats hat i meant then. (f o g)

Answer 13

take f(x) and wherever you see an x, write a g instead.

Answer 14

then, wherever you wrote a g, write in the definition of g(x)

f o g = f(g)

Answer 15

yeah i still dont get it. people have tried to explain it to me several times and i still dont get it.

Answer 16

what is f(x) defined as?

Answer 17

I think this stems from not having a solid grasp on what a mathematical function really is. Take a bit to read through this page.
