Question

I don't known if I am right on this one :\

Answer 1

To solve this problem, you just need to add the two functions together, making sure that you watch your signs.

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

After we simplify and combine like terms, we get:

f(x) + g(x) = 2x - 7 - 6x - 3
= -4x - 10

The domain is all real numbers because both of the functions being added together also have a domain of all real numbers.

Therefore, the answer you have selected (the last option) is correct.

Hope this helps!
