Question

Given the definitions of f(x) and g(x) below, find the value of (gºf)(-5).

Answer 1

Answer:

(g ￮ f)(- 5) = 4

Step-by-step explanation:

evaluate f(- 5) then substitute the value obtained into g(x)

f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then

g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4

(g ￮ f)(- 5) = 4
