Question

What is g(f(x)) if f(x) = 3x + 2 and g(x) = -2x + 4?

Answer 1

⇒g(f(x)) means that in the function g(x) insert/plug in what f(x) is equal to in the place of x. f(x)= 3x+2 meaning in the place of x in g(x) insert 3x+2 and simplify.

`g(f(x))=-2(3x+2)+4\\g(f(x))=-6x-4+4\\g(f(x))=-6x`

Attached is the solution of what g(f(x)) is equal to.
