Answer 1

B.

General Formulas and Concepts:

• Order of Operations: BPEMDAS
• Equality Properties

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
