Question

F(x) = 2x – 1 g(x) = 7x – 12 What is h(x) = f(x) + g(x)?

A. h(x) = 9x – 13
B. h(x) = 9x – 12
C. h(x) = –5x + 11
D. h(x) = 5x – 13

Answer 1

Answer: A

Explanation:

Answer 2

Hello!

The answer is:

A.

`h(x)=9x-13`

Why?

To solve the problem, we need to perform the shown operation.

We have the functions:

`f(x)=2x-1\\g(x)=7x-12`

So, performing the following operation, we have:

`f(x)+g(x)=h(x)`

`h(x)=f(x)+g(x)=(2x-1)+(7x-12)=7x+2x-1-12=9x-13`

`h(x)=9x-13`

Hence, we have that the correct option is:

A.
`h(x)=9x-13`

Have a nice day!
