Answer:

(f - g)(x) = 2x - 3

General Formulas and Concepts:

Pre-Algebra

  • Distributive Property

Algebra I

  • Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = 3x - 1

g(x) = x + 2

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

Step 2: Evaluate

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