Uncheck the upper box to hide the graph and arrows on the diagram
for the function $h(x) = \ln(x)$.
Check the lower box to show the graph and arrow on the diagram
for the functions $f(x) = \log_2(x)$ and $g(x) = \log_3(x)$.
Use the $y_{zoom}$ slider to adjust the scale of the target axis on the mapping diagram.
