Let

, switch theand thein the equation and solve for.See part (a).

Let

. Switchand. Multiply both sides of the equation byto remove the fraction. Distribute and then rewrite the equation so that all the

*y*-terms are on the left side and everything else is on the right side.Your equation should look like this:

. Factor the left side of the equation and divide both sides byto get *y*by itself.Graph the equation on a graphing calculator to see why this equation is its own inverse.
