causes its “
R
” or “

• The graph properties operation can be performed only for the graph that is on the left side
of the Dual Graph graph screen.

R

Example Graph
y = x(x + 1)(x – 1) in the main screen and sub-screen.
Use the following V-Window settings.
(Main Screen) Xmin = –2, Xmax = 2, Xscale = 0.5
Ymin = –2, Ymax = 2, Yscale = 1
(Sub-screen) Xmin = –4, Xmax = 4, Xscale = 1
Ymin = –3, Ymax = 3, Yscale = 1
