SHIFT/CHANGE FUNCTIONS
<Example>
The CHANGE function is explained using the graph for “Y = X
2
”, also used in the
SHIFT function.
1. Press
Ï
B
>. (Touch [B
CHANGE] and [Y= X
2
] with the pen.) Sets the
CHANGE mode of “Y = X
2
”.
2. Press

. Sets the CHANGE mode. The screen
shown to the right will appear.
The cursor with a shape of “
”, different from that in
the SHIFT screen, will appear on the graph for “Y =
X
2
”.
This indicates the directions in which the graph can
be changed (only upward and downward in this
example). The same rule is applied to other equa-
tions.
3. Press ≤. (Touch the upper arrow of “
” with the
pen). The cursor frame “ ” moves upward and an
arrow will appear toward the cursor.
Numeric values displayed on the bottom of the
screen show changes in the graph based on
changes in the coordinates.
(The example shown to the right means that you wish to change the graph for “Y =
X
2
”, passing through the coordinates (1, 1), to the graph passing through (1, 2).)
4. Press
®
. Sets the moved graph.
When setting the moved graph, the moved graph is
displayed by a solid line, and the cursor is also
moved to the graph after it has been changed.
The expression showing that the equation has
changed from “Y = X
2
” to “Y = 2X
2
” will appear on the
right portion of the screen.
5. Press
®
. Stores the equation “Y = 2X
2
”.
