Provide an appropriate response.Your classmate missed the lecture on how to find the inverse of a one-to-one function. When your classmate calls you on the phone for an explanation, what will you say to explain the process?
What will be an ideal response?
Answers may vary. One possibility: in an equation written in the form the first step is to reverse x and y. Then, solve for y. Finally, replace y with
To determine the inverse of a set of ordered pairs, simply reverse the order of the x- and y- coordinates for each individual ordered pair.
