If h(x) = x – 7 and g(x) = x², find the value that is equivalent to (g*h)(5)?

We will use the concept of functions in order to find the required answer.

Answer: (g*h)(5) = -50

Let us see how we will use the concept of functions in order to find the required answer.

Explanation:

We have been given two functions, h(x) = x – 7 and g(x) = x²

(g * h) (x) = g(x) × h(x)

= x³ - 7x²

Substitute 5 for x in (g * h) (x) = x³ - 7x² to find (g * h)(5).

(g * h)(5) = 5³ - 7× 5² = -50

Hence, (g * h)(5) = -50
