General Formulas and Concepts:

  • Compositions of Functions

Order of Operations: BPEMDAS

Explanation:

Step 1: Define

f(x) = 3x + 10

g(x) = x - 2

f(-10) is x = -10

Find g(f(-10))

Step 2: Solve:

  1. Find f(-10). Substitute: f(-10) = 3(-10) + 10
  2. Multiply: f(-10) = -30 + 10
  3. Add: f(-10) = -20
  4. Substitute: g(-20) = -20 - 2
  5. Subtract: g(-20) = -22
