$f(x)=a_n(x−h)^{-n}+k = \frac
{a_n}{(x-h)^n} + k.$ $n>0$

- Move the slider to change the value of $n, h, k$, and $a_n $.
- Check the box to see the table data visualized as arrows on
the mapping diagram and points on the graph for the function.

- 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 0.1.
