Random Piecewise Function Creator and Grapher

This Geogebra will make an endless number of piecewise functions. It will show the correct inequalities for the domain and correct "dots" on the lines. Each side of the graph can be set to different degrees (constant, linear, quadratic, etc) and the labels can be turned on and off for classroom use. The function should show up on the left but does not seem to do so in the web version. Not sure why.
