Step-by-step explanation:

Step 1: Define

g(x) = -x² + 10x - 3

g(9) is x = 9

Step 2: Evaluate

1. Substitute in x:                    g(9) = -(9)² + 10(9) - 3
2. Exponents:                          g(9) = -(81) + 10(9) - 3
3. Multiply:                               g(9) = -81 + 90 - 3
4. Add:                                     g(9) = 9 - 3
5. Subtract:                              g(9) = 6
