Question

1. Let f(x) = 4x - 32 and g(x) = 4x.
What is (f ? g)(x)?

Answer 1

do you mean f(g(x))?

Answer 2

yes

Answer 3

f(x) = 4x-32
f(m) = 4m-32
f(2f) = 8f-32
f(2x) = 8x-32

f(a) means, replace all the x's in f(x) with a.

so f(g(x)) = f(4x)

Can you do this now?

f(g(x)) means take what ever g(x) is and put that in for the x's in f(x).

Answer 5

whats the method did you used to solve this problem

Answer 6

replace the x in "4x-32" with "4x"

f(g(x))=4(4x) - 32

Answer 7

u substitute gx into fx

Answer 8

Let f(x) = 4x - 32 and g(x) = 4x.

f(g(x)

this means that you need to consider what ever in the g(x) = x

and then replace it with x in f(x)

gx=x=4x

4(4x) -32

16x^2 -32
