    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
