If f(x) = 5x – 2 and g(x) = 2x + 1, find (f+9)(x).
a)3x-1
b)7x-1
c)7x-3
d)4x-3

B) 7x - 1

In this question, you're going to solve by adding both f(x) and g(x) together.

You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.

What (f+g)(x) looks like:

(5x - 2 + 2x + 1)(x)

What you would do is solve to get your answer. You're going to be combining like-terms and adding.

When you're done solving, you should get 7x - 1

This means that B) 7x - 1 would be the correct answer.
