Example OAF.RF.0:  Suppose $y$ is a function of $x$ given by the equation $f(x) = \frac 3 {x-2}$.
The GeoGebra applet gives a spreadsheet, a graph and a mapping diagram for this function.
You can explore other similar related rational functions- by changing the slider values of $A$ and $h$.
The spreadsheet shows a selection of the values this function.
The graph frame shows the graph of the table values of the function $f$ as well as the visualization of the graph of (all the values of) the function.
The mapping diagram frame shows a mapping diagram with a moveable point paired with a point on the graph of $f$.
Checking the box in either frame will show arrows on the diagram and points on the graph that correspond to the values on the spreadsheet table for $f$.
This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com
