Specify the graph and determine the local minimum value.

!5(G-Solv)

3(MIN) cw

• If there is more than one local maximum/minimum value, you can use d and

e to move between them.

• If there is only one graph, pressing 2 (MAX) / 3 (MIN) directly displays the

local maximum/minimum value (selection of the graph is not required).

•Note that the above operation can be performed on rectangular coordinate (Y=)

and inequality graphs only.

!5(G-Solv)

4(Y-ICPT)

(This puts the unit into standby waiting

for selection of a graph.)

Determine the y-intercept.

• y-intercepts are the points where the graph intersects the y-axis.

• If there is only one graph, pressing 4 (Y-ICPT) directly displays the

y-intercepts (selection of the graph is not required).

•Note that the above operation can be performed on rectangular coordinate

(Y=) and inequality graphs only.
