Question

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

O A. (f+ g)(x) = -x + 3
O B. (f+ g)(x) = x - 7
O c. (f+ g)(x) = -7x-3
O D. (f+ g)(x) = 7x - 7

Answer 1

B

Explanation:

you are just combining like terms since you are adding the equations together

(-3x-5) + (4x-2)

-3x + 4x = x

-5 + -2 = -7

so altogether

x -7
