Aside from color-coding, what other “important mathematical features” are included in the graph?
Certain functions have breaks, discontinuities, and asymptotic behaviors, which all good math textbooks illustrate by using dashed lines and small empty or filled circles. The illumination of these important mathematical features is an invaluable addition to a graph, required to visually identify the special attributes of a function. WebGraphing.com automatically includes these features in its graphs, while standard graphing calculators do not. What is Smart Zooming? After seeing the complete graph, if you enter only the lower (Xmin) and upper (Xmax) bounds on the x-values and click the Graph Again button, Smart Zooming takes over and WebGraphing.com automatically determines optimal lower (Ymin) and upper (Ymax) bounds for the y-values; the resulting viewing window includes all the important mathematical features on your selected interval (Xmin,Xmax). This is convenient and more powerful than ordinary proportional zooming since you don’t have to go through trial and error to get an opt
