Given f(x) = 3x-10 and g(x) = 12x +8, solve for (f+g)(x) a. (f+g)(x) = 15x-2 b. (f+g)(x) = 9x-2 c. (f+g)(x) = 15x+2 d. (f+g)(x) = 36x^2-120x

The correct answer is A) (f+g)(x) = 15x - 2

Step-by-step explanation:

In order to complete a composite addition function, you need to add the two functions together combining like terms.

(f+g)(x) = f(x) + g(x)

(f+g)(x) = 3x - 10 + 12x + 8

(f+g)(x) = 15x - 2
