Answer:

Answer is (f - g)(x)  = -7x - 3

Step-by-step explanation:

We have:

f(x) = -3x - 5

g(x) = 4x -2

We need to find: (f - g)(x)

So, we can write:

(f - g)(x) = f(x) - g(x)

           = (-3x -5) - (4x - 2)

           = -3x - 5 -4x + 2

           = - 3x - 4x -5 +2

  (f - g)(x)  = -7x - 3

So we get  (f - g)(x)  = -7x - 3
