Step-by-step explanation:

Step 1: Define

Identify

f(x) = 2x²

Step 2: Evaluate

1. Substitute in x [Function f(x)]:                                                                           f(-3) = 2(-3)²
2. Exponents:                                                                                                       f(-3) = 2(9)
3. Multiply:                                                                                                             f(-3) = 18
