Which of the following expressions is the inverse of the function y = x - 2 over 3?

To find the inverse, you can either do this:

y = (x-2) / 3 * switch x and y

x = (y-2) / 3 * multiply 3 on both sides

x (3) = ((y-2) / 3) (3) * the three cancels out on the right side

3x=y-2 * add the 2 on both sides

3x+2=y-2+2 * simplify

Final answer should be : 3x+2=y (inverse)
