B.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

Step 1: Define function

f(x) = 8x + 4

Step 2: Prep

  1. Rewrite:                         y = 8x + 4
  2. Swap x and y:               x = 8y + 4

Step 3: Find Inverse (Solve for y)

  1. Subtract 4 on both sides:                    x - 4 = 8y
  2. Divide both sides by 8:                       (x - 4)/8 = y
  3. Rewrite:                                                 y = (x - 4)/8
  4. Rewrite:                                                f⁻¹(x) = (x - 4)/8
