Step-by-step explanation:

Step 1: Define

Identify

f(x) = 3x - 1

g(x) = x + 2

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

Step 2: Find

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