8. Modifying a Graph
A Modify function lets you modify the value of a variable in a graph expression (for example,
the value of A in Y = AX
2 ) from the graph screen and view how the change affects the graph.
k Modify Function Overview
The Modify function can be used in the Graph mode and Conic Graphs mode. To execute
the Modify function in the Graph mode, display the graph relation list screen and press
5(MODIFY). In the Conic Graphs mode, display the coefficients input screen and press
1(MODIFY).
The following shows an example of the graph screen while the Modify function is running.
Graph expression Graph
Graph expression variables and
their current values
Step value
• The graph expression variables and their current values, and a step value are displayed in
the lower left corner of the screen while the Modify function is running. The variable (or step
value) that you can modify is displayed in magenta.
• Use d and e to modify the value of the magenta colored variable. Each press of d or
e changes the magenta value by the amount specified by the step value.
Important!
• You can use the Modify function to modify only one graph expression, and the graph
expression being modified can contain at least one and no more than five variables. If these
conditions are not satisfied, attempting to execute the Modify function will cause an error.
When there are multiple expressions graphed and only one of them includes variables, you
can execute the Modify function to simultaneously graph the expression that contains the
variables and the expressions that do not contain any variables.
• Note that the Modify function cannot be executed in the case when there is more than one
expression containing variables.
