5. Press
' '
to shift the
graph to the right in two increments
(for the
+
X direction).
The upper right portion of the
screen will change as shown on the
right, and only the “Y = X
2
+
1”
graph is shown on the screen.
This means that the graph can be shifted based on the newly
shifted equation “Y = X
2
+
1”.
6. Press
E
.
The graph is shifted to the right by 2
increments and the equation is
changed from “Y = X
2
+
1” to “Y = (X
–
2) 2
+
1”.
(The graph for “Y = X 2
+
1” is changed to the dotted line.)
7. Press
E
to register the equation (graph) “Y= (X
–
2) 2
+
1”.
The registered equation “(X
–
2) 2
+
1” is added to under “Y = X 2 ” on the
bottom half right screen. (Up to ten
equations, 1 to 9, and 0, including
the base equation (Y = X
2
) can be
registered.)
