3. Press
{
.
The graph “Y = X
2
” is shifted by 1 (Y
= 1) upward.
The cursor icon will change to “ ”
indicating that the graph will be
shifted upward from the start point (0, 0) in the next step.
The
∆
X and
∆
Y values at the bottom of the graph indicates the
amount of shift amount in the X and Y directions.
4. Press
E
.
The line type of the original graph
(Y = X
2
) is changed to the dotted
line (....) and the shifted graph is
drawn in the solid line (—).
The upper right portion of the screen shows how the equation
is changed according to the graph shift. In this case, it says “Y
= X
2
” is changed to “Y = X
2
+
1”.
The cursor position is also shifted in the same direction and
the cursor icon will be changed to the four arrow type, indicat-
ing that shift feature is now in the standby mode.

graph can be shifted
(When all the four
arrows are shown, the
graph can be shifted
for four directions.)
