Input a storage area number and then press one of the following function keys to
recall the corresponding graph function stored in that storage area.
1 (Y) ............ Rectangular coordinate or inequality function
2 (
r)............. Polar coordinate function
3 (Xt) ........... Parametric graph function Xt
4 (Yt) ........... Parametric graph function Yt
5 (X) ............ X=constant graph function
Example To recall and draw the graph for the rectangular coordinate
function y = 2 x
2
– 3, which is stored in storage area Y2
Use the following View Window parameters to draw the graph.
Xmin =–5 Ymin =–5
Xmax = 5 Ymax = 5
Xscale = 1 Yscale = 1
