Explanation:

Step 1: Define

g(x) = -5x + -7

x = -3, 0, 4

Step 2: Evaluate

x = -3

1. Substitute in x: g(-3) = -5(-3) + -7
2. Multiply: g(-3) = 15 + -7
3. Add: g(-3) = 8

x = 0

1. Substitute in x: g(0) = -5(0) + -7
2. Multiply: g(0) = 0 + -7
3. Add: g(0) = -7

x = 4

1. Substitute in x: g(4) = -5(4) + -7
2. Multiply: g(4) = -20 + -7
3. Add: g(4) = -27
