Red Deer teacher, Rene Vandervlis, recommended this online graphing calculator, noting that students “can graph any function, add sliders to show how the graph changes as certain parameters do, and print the graphs or import them into other documents. It also graphs and shades inequalities, and has features that allow you to restrict the domain and range.” Rene goes on to suggest that this might be a good alternative to TI devices.
