Answer:

A. (f - g)(x) = -7x - 3

General Formulas and Concepts:

Algebra I

  • Composite Functions
  • Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = -3x - 5

g(x) = 4x - 2

(f - g)(x) is f(x) - g(x)

Step 2: Find (f - g)(x)

  1. Substitute:                    (f - g)(x) = -3x - 5 - (4x - 2)
  2. Distribute -1:                 (f - g)(x) = -3x - 5 - 4x + 2
  3. Combine like terms:    (f - g)(x) = -7x - 3
