Find (fog)(x). f(x) = 2x g(x) = x + 6

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

(f•g)(x)=2x²+12x

Step-by-step 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.

table 3 represents a direct variation function. : )

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
