Question

If f(x) = -3 -5 and g(x) =4x - 2, find (f+g)(x)

Answer 1

According to the problem, we just have to sum the given functions f(x) plus g(x)

`(f+g)(x)=f(x)+g(x)=-3x-5+4x-2`

We just have to reduce like terms. -3x and 4x are like terms; -5 and -2 are like terms.

`(f+g)(x)=x-7`

Hence, the right answer is B.
