Step-by-step explanation:

Step 1: Define

f(x) = 4x - 2

x = 3

Step 2: Evaluate

1. Substitute in x [Function]:                                                                                f(3) = 4(3) - 2
2. Multiply:                                                                                                             f(3) = 12 - 2
3. Subtract:                                                                                                            f(3) = 10
