Answer 1

@jim_thompson5910 same thing just reverse right?

Answer 2

yep, you start with f(x) now

then you replace every x with g(x)

Answer 3

oh

Answer 4

f(x) = 2x + 3

f(g(x)) = 2*g(x) + 3 .. replace every x with g(x)

f(g(x)) = 2*(2x^2+2x) + 3 ... replace g(x) on the right with 2x^2+2x


simplify
