Answer:

f(x + 3) = x² + 3x - 2

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Expand by FOIL (First Outside Inside Last)

Explanation:

Step 1: Define

f(x) = x² - 3x - 2

f(x + 3) is x = x + 3

Step 2: Find

  1. Substitute: f(x + 3) = (x + 3)² - 3(x + 3) - 2
  2. Expand by FOILing: f(x + 3) = x² + 6x + 9 - 3(x + 3) - 2
  3. Distribute 3: f(x + 3) = x² + 6x + 9 - 3x - 9 - 2
  4. Combine like terms: f(x + 3) = x² + 3x - 2
