Input three sets of coordinates and this program will try to graph a quadratic equation to fit the data, listed at the bottom. Coordinates may be entered without parentheses. Once the equation has been calculated, the graph can be traced by pressing the left or right arrow keys; the coordinates of the tracer are listed at the top of the window. The speed at which the line is traced can be adjusted with the Trace Speed slider. As of the current date, there is no ability to zoom in or move the axes.
