2. CHANGE Function

The SHIFT function previously described allows you to move the graph and view the
relationship between the moved graph and its equation.
The CHANGE function shows the relationship between the graph and equation by
changing the shape of the graph.
For example, using this function, you may view changes such as "Y = 2X

3X " based on "Y = X

The following shows the built-in equations, change steps, and movable range appli-
cable to the change function.
(In the same manner as described in the SHIFT function, the trigonometric functions for
different angles are also included.)
