Question

If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).

Answer 1

(f + g)(x) = 4x + 1

Explanation:

(f + g)(x) - f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1

Answer 2

4x+1

Explanation:

Since you're finding (f+g) (x), it means you are adding f(x) and g(x) together.

so you add: (3x-1) and (x+2)

combining like terms, you get 4x and 1, which means (f+g)(x)= 4x+1
