and pressing ¸.
Finding a Zero, Minimum, or Maximum within an Interval
1. From the
Graph screen, press ‡ and select 2:Zero, 3:Minimum, or 4:Maximum.
2. As necessary, use D and C to select the applicable function.

3. Set the lower bound for x. Either use A and B to move the cursor to the lower bound
or type its x value.
4. Press ¸. A 4 at the top of the screen marks the lower bound.
Finding the Intersection of Two Functions within an Interval
1. From the
Graph screen, press ‡ and select 5:Intersection.
2. Select the first function, using D or C as necessary, and press ¸. The cursor
moves to the next graphed function.
3. Select the second function, and press ¸.
4. Set the lower bound for x. Either use A and B to move the cursor to the lower bound
or type its x value.
