Step-by-step explanation:

Step 1: Define

f(x) = -x² + 10x - 6

f(-5) is x = -5

Step 2: Evaluate

Substitute:                    f(-5) = -(-5)² + 10(-5) - 6Exponents:                   f(-5) = -(25) + 10(-5) - 6Multiply:                        f(-5) = -25 - 50 - 6Subtract:                       f(-5) = -75 - 6Subtract:                       f(-5) = -81
