Even though … WebTo avoid this we simply interchange the roles of x and y before we solve. Example 3. f (x) = x3 + 2. This is the function we worked with in Exercise 1. From its graph (shown above) we see that it does have an inverse. (In fact, its inverse was given in Exercise 1.) Step 1. y = x 3 + 2. Step 2. x = y 3 + 2.
