2: ``Function'' - Enter the function here. An equals sign is not necessary. Just give the right hand side of the function. LON-CAPA variables are usable as well to allow individualized problems for each student. The syntax must be syntax recognized by GeoGebra. To test syntax for Geogebra directly, visit http://www.geogebra.org/webstart/geogebra.html .

4: ``Initial x-value'' and ``Final x-value'' - The function does not need to span the entire graph. It is possible to create a piecewise function by defining the x-values over which each function is to be shown.

8: ``Color'' - To change the color of the background function, enter the hex code for that color here. The default is 000000 (black). It is recommended to choose a color other than green, since it is easily confused with being the answer.
