6. Press 6(DRAW).
• This draws a quadratic regression graph and overlays it over the original graph.
•To delete the overlaid quadratic regression graph, press 3(SKTCH) and then b(Cls).
k Overlaying a Y=f(x) Graph on a Sampled Result Graph
Use the following procedure when you want to overlay a Y=f(x) graph on the sampled result
graph.

u To overlay a Y=f(x) graph on an existing graph
1. On the graph screen, press 5(Y=fx).
• This displays the graph function list. Any functions you have previously input on the

2. Input the function you want to graph.
•To input a function, use the f and c cursor keys to move the highlighting to the line
where you want to input it, and then use the calculator keys for input. Press w to store
the function.
3. On the graph function list, specify which functions you want to graph.
• Graphing is turned on for any function whose “=” symbol is highlighted. To toggle
graphing of a function on or off, use the f and c cursor keys to move the highlighting
to the function, and then press 1(SEL).
4. After the graph function list settings are configured the way you want, press 6(DRAW).
• This overlays graphs of all the functions for which graphing is turned on, over the graph
that was originally on the graph screen.
•To delete the overlaid graph, press 3(SKTCH) and then b(Cls).
