Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below. (f + g)(x) = 15x − 2 (f + g)(x) = 9x − 2 (f + g)(x) = 15x + 2 (f + g)(x) = 36x2 − 120x

First option is correct.

Step-by-step explanation:

Since we have given that

We need to find the addition of two functions i.e. f and g.

So, it becomes,

Hence, the addition of two functions is (f+g)(x)=15x-2.

Therefore, first option is correct.
