Question

Pleaseeee answer, thank you

Answer 1

58

Explanation:

to evaluate g(f(h(2)))

evaluate h(2) and substitute this value into f(x) , then substitute the value obtained here into g(x)

h(2) = -
`(1)/(2)` × 2 - 4 = - 1 - 4 = - 5 , then

f(- 5) = (- 5)² - 4 = 25 - 4 = 21 , then

g(21) = 3(21) - 5 = 63 - 5 = 58
