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 $f$.
