Given functions f and​ g, find fg.

Question

​f(x)=2x+8​, g(x)=5x-2

Answer 1

I'm not sure if you meant multiplication, (f·g)(x), or composition, f(g(x)). I'll do both:

Multiplication: (f·g)(x) = f(x)·g(x) = (2x+8)(5x-2) = _____? FOIL it out then combine like terms

Composition: f(g(x)) = 2g(x) + 8 = 2(5x-2) + 8 = _______? FOIL it out then combine like terms
