Question

Given the functions below, find (g•h) (1).

g(x) = х^2 +4+ 2х
h(x) = — 3х + 2
-7
-30
35
7

Answer 1

-7

Explanation:

We are given the following functions:

`g(x) = x^2 + 4 + 2x`

`h(x) = -3x + 2`

(g•h) (1)

The multiplication is:

`(g * h)(1) = g(1) * h(1)`

So

`g(x) = 1^2 + 4 + 2(1) = 7`

`h(1) = -3(1) + 2 = -3 + 2 = -1`

Then

`g(1) * h(1) = 7(-1) = -7`

So -7 is the answer.
