Step-by-step explanation:

Step 1: Define

f(x) = 3x - 7

g(x) = 2x² - 3x + 1

h(x) = 4x + 1

k(x) = -x² + 3

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

1. Substitute:                              k(x) + g(x) = -x² + 3 + 2x² - 3x + 1
2. Combine like terms (x²):        k(x) + g(x) = x² + 3 - 3x + 1
3. Combine like terms (Z):         k(x) + g(x) = x² - 3x + 4
