A Simple Rational Function & Its Inverse
by Mike Martin

On this page, you can vary the parameters and graphing bounds for a simple rational function and, in turn, its inverse.   The rational function is given by

ratio of two degree-1 polynomials.

Once the parameters and bounds are set you can plot both functions and the identity line, y = x.   Enter in the bounds for the x-variable and then the bounds for the y-variable are the same as those for the x-variable.

Select the parameter values and plotting bounds, then press the "Evaluate" button.

b =  

c =
