Question

Let f(x) = 5 - x and g(x) = 2x - 1. Perform the following operation: (f + g)(-2).

Answer 1

(f + g)(-2) = 2

Explanation:

Step 1: Define

f(x) = 5 - x

g(x) = 2x - 1

Step 2: Find (f + g)(x)

(f + g)(x) = 5 - x + 2x - 1

(f + g)(x) = x + 4

Step 3: Find (f + g)(-2)

(f + g)(-2) = -2 + 4

(f + g)(-2) = 2
