Question

Given the functions below, find (h.g) (4).
g(x) = 3x +3
h(x) = -4x + 1

Answer 1

(h·g)(4) = -225

Explanation:

We assume your (h.g) is supposed to represent the product h(x)g(x). Filling in the numbers and doing the arithmetic, we have ...

(h·g)(4) = h(4)·g(4) = (-4(4)+1)(3(4)+3) = (-15)(15)

(h·g)(4) = -225
