GRAPHING FUNCTIONS
[3 Minimum]:
• Press 3.
The cursor pointer moves to the minimum point of the
graph for “Y1 = X
2
– 5”.
• At this time, the coordinates will appear on the bottom
of the screen.
• To move to another graph, press ≥ or ≤.
If the minimum point cannot be calculated, the error message, “No Solution”, will appear
and show that the cursor pointer cannot be moved.
[4 Maximum]:
• Press 4.
• In the previous example, the maximum point cannot be calculated and therefore the
error message “No Solution” will appear on the screen.
• If the graph “Y1 = –X
2
+ 2” shown to the right is
displayed, the cursor moves to the maximum point.
[5 X_Incpt]:
• Press 5.
If there is more than one
intersection, press Ï ˘
5 to move the cursor
pointer to the next intersection.
