So if youre asked to graph a function and its inverse all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Graphing and Inverse Functions Exercises These are homework exercises to accompany Corrals Elementary Trigonometry Textmap. You can think of the relationship of a function and its inverse as a situation where the x and y values reverse positions.
Let us return to the quadratic function latexfleftxrightx2latex restricted to the domain latexleft0infty rightlatex on which this function is one-to-one and graph it as in Figure 7.
This is done to make the rest of the process easier. If the initial function is not one-to-one then there will be more than one inverse.
