Step-by-step explanation:

Step 1: Define

f(x) = 3x² + 2x - 3

f(3) is x = 3

Step 2: Evaluate

Substitute in x:                    f(3) = 3(3)² + 2(3) - 3Exponents:                          f(3) = 3(9) + 2(3) - 3Multiply:                               f(3) = 27 + 6 - 3Add:                                     f(3) = 33 - 3Subtract:                              f(3) = 30
