Step-by-step explanation:

Step 1: Define

Identify

f(x) = 5x - 2

g(x) = 2x + 1

Step 2: Find

1. Substitute in functions:                                                                                      (f + g)(x) = 5x - 2 + 2x + 1
2. Combine like terms:                                                                                         (f + g)(x) = 7x - 1
