Answer:

A

Step-by-step explanation:

We are given the two functions:

f(x)=4x+5\text{ and } g(x)=x^2-2x-2

And we want to find:

(f+g)(x)

This is equivalent to:

=f(x)+g(x)

Substitute:

=(4x+5)+(x^2-2x-2)

Rearrange:

=(x^2)+(4x-2x)+(5-2)

Combine like terms. Hence:

(f+g)(x)=x^2+2x+3

Our answer is A.
