Question

Given f (x) = -4x + 4, solve for x when f (x) = 0

Answer 1

x = 1

Explanation:

Given:

• f(x) = -4x + 4
• f(x) = 0

We are asked to solve for x when the function is equal to zero.

We should have: 0 = -4x + 4

Solve

1. Subtract 4 from both sides

0 - 4 = -4x + 4 - 4

-4 = -4x

2. Divide both sides by -4

-4 ÷ -4 = -4x ÷ 4

1 = x
