Question

Given the definitions of f(x) and g(x) below, find the value of (g o f) (9)

F(x)= - x+9
G(x)= x^2 + 7x - 6

Answer 1

-6

Explanation:

(g o f)(9) is equivalent to g(f(9))

In this case, solve for f(9) where 9 replaces the x

-(9)+9

0

After that, you are now solving for g(0) because you are following PEMDAS

(0)^2+7(0)-6

-6
