Question

Which of the following expressions is the inverse of the functiony equals quantity x minus 2 divided by 3?

Answer 1

Answer:

$y = 3x + 2$

Step-by-step explanation:

Write the equation:

$y = \frac{x - 2}{3}$

Step 1. Change the x to the y and the y to the x.

$y = \frac{x - 2}{3}$ → $x = \frac{y - 2}{3}$

Step 2. Multiply both sides by 3.

$y - 2 = 3x$

Step 3. Add 2 to both sides.

$y = 3x + 2$
