Question

Find (fog)(x). f(x) = 2x

g(x) = x + 6

write your answer as a polynomial in simplest form.
(f•g)(x)=​

Answer 1

Answer: (f•g)(x)=​2x²+12x

Explanation:

(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.

(f•g)(x)=​2x(x+6) [distribute by FOIL]

(f•g)(x)=​2x²+12x

Now, we know that (f•g)(x)=​2x²+12x.
