Step-by-step explanation:

Step 1: Define

Identify

f(x) = 1 - x² + x³

f(-1) is x = -1 for the function f(x)

Step 2: Evaluate

1. Substitute in x [Function f(x)]:                                                                           f(-1) = 1 - (-1)² + (-1)³
2. Exponents:                                                                                                        f(-1) = 1 - 1 - 1
3. Subtract:                                                                                                            f(-1) = -1
