Question

If f(x) = 2x + 3 and g(x) = 4x - 5, what is f(g(x))?

Answer 1

When they say f(g(x)) notice they took what was f(x) and changed the "x" to "g(x)"

Answer 2

Thats exactly what we are going to do too!! Change all the x's in f(x) to what g(x) is.

Answer 3

Basically this means that you have to replace x of f(x) by 4x - 5..

Answer 4

i know its: 2(4X-5) + 3. I distribute, right?

Answer 6

8x - 10 + 3
