Answer:

(f ○ g)(2) = 8 , (g ○ f)(- 5) = 22

Explanation:

(a) to evaluate (f ○ g)(2)

evaluate g(2) then substitute the value obtained into f(x)

g(2) =
(2-6)/(2) =
(-4)/(2) = - 2 , then

f(- 2) = 2(- 2)² = 2(4) = 8

(b)

to evaluate (g ○ f)(- 5)

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

f(- 5) = 2(- 5)² = 2(25) = 50 , then

g(50) =
(50-6)/(2) =
(44)/(2) = 22
