Question

I need help with this question

Answer 1

Answer: First option.

Explanation:

Given the function f(x):

`f(x)=2x-7`

And the function g(x):

`g(x)=-6x-3`

You need to add them to get
`f(x)+g(x)`. Then:

`f(x)+g(x)=(2x-7)+(-6x-3)`

Therefore, when you add the like terms you get that
`f(x)+g(x)` is:

`f(x)+g(x)=2x-7-6x-3`

`f(x)+g(x)=-4x-10`

Since it is a linear function, the Domain is: All real numbers.

You can observe that the result obtained matches witht the first option.
