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.

(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.
