(

) Type Function Graphs and 
Parametric Function Graphs
You can use the Differential Equation Graph application to graph 
f
(
x
) type function graphs 
and parametric function graphs, the same way as you do with the Graph & Table application. 
These types of graphs can be overlaid on differential equation graphs.
