Explanation:

Step 1: Define

g(x) = 2x³ + 2x² - 4x - 9

g(-3) is x = -3

Step 2: Evaluate

1. Substitute: g(-3) = 2(-3)³ + 2(-3)² - 4(-3) - 9
2. Exponents: g(-3) = 2(-27) + 2(9) - 4(-3) - 9
3. Multiply: g(-3) = -54 + 18 + 12 - 9
4. Add: g(-3) = -36 + 12 - 9
5. Add: g(-3) = -24 - 9
6. Subtract: g(-3) = -33
