Step-by-step explanation:

Step 1: Define

f(x) = 1 - x

g(x) = x² + 2x - 5

(f + g)(x) is f(x) + g(x)

Step 2: Solve

Substitute in functions:                                                                                     (f + g)(x) = (1 - x) + (x² + 2x - 5)Combine like terms (x):                                                                                    (f + g)(x) = x² + x - 5 + 1Combine like terms:                                                                                         (f + g)(x) = x² + x - 4
