• When students are taught to graph functions, they typically are taught using a graphing calculator. But two free online programs, GeoGebra and Desmos, allow students to do much more. Here, Bready and Sterken show the steps needed to insert a photograph into each program and to create a polynomial to fit the image in the photograph. They compare the pros and cons of these programs and discuss extensions for their use in a mathematics classroom.
