IEditing and Deleting Functions

STo edit a function in memory

Example	To change the expression in memory area Y1 from y = 2x2 – 5 to
	y = 2x2 – 3

2.Press (TYPE)(CONV).

3.Select the function type you want to change to.

Example	To change the function in memory area Y1 from y = 2x2 – 3 to
	y < 2x2 – 3
	(TYPE)(CONV)(Y<) (Changes the function type to “Y<”.)

*1 The function type can be changed for rectangular coordinate functions and inequalities only.
