Explanation:

Step 1: Define

Identify

f(x) = 3x - 1

g(x) = x + 2

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

Step 2: Find

  1. Substitute in functions: (f - g)(x) = 3x - 1 - (x + 2)
  2. [Distributive Property] Distribute negative: (f - g)(x) = 3x - 1 - x - 2
  3. [Subtraction] Combine like terms (x): (f - g)(x) = 2x - 1 - 2
  4. [Subtraction] Combine like terms: (f - g)(x) = 2x - 3
