Answer:

O C. (f – g)(x) = -3x^2 - x - 4

Step-by-step explanation:

I will assume that f(x) is -4x^2- 6x - 1

f(x) = -4x^2 - 6x - 1

g(x) = -x2 - 5x + 3

(f - g)(x)= -4x^2 - 6x - 1  - (-x2 - 5x + 3)

Distribute the minus sign

(f - g)(x)= -4x^2 - 6x - 1  +x2 + 5x - 3

Combine like terms

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