Graphing Equations and Plotting Points

Graph equations by typing into the box.  Enter polynomial, rational, trigonometric, and logarithmic functions.  Two functions (of x or y) can be graphed at once. Screenshot of graphing equation

Graph inequalities just by changing the comparison.  When graphing two inequalities in HandyGraph, you can shade both or only the intersection.

Plot points quickly by clicking on the graph with the Point Tool or enter the coordinates into a point table.  Set the style and color independently for each of the four point tables.
