Table LF1 shows a selection of the values
this function relates.
Graph LF1 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 for the interval domain $[-5,5])$.
Diagram LF1 shows the mapping diagram for most of the
table values of the function $f$.
