- Insert your own polynomial functions for $P(x)$ and $Q(x)$.
- Check the box to see the table data visualized as arrows on the mapping diagram and points on the graph for the function.
- Move the points $a$ and $b$ on the mapping diagram to change
the interval for the arrows and points.

- Select the point $x$ in the mapping diagram to move the point
by mouse or use the scroll up or down key to move by
increments of 1.
