!5(G-Solv)
Specify the graph and determine the minimum.
3(MIN) cw
• If there is more than one maximum/minimum, you can use d and e to move
between them.
• If there is only one graph, pressing 2 (MAX) / 3 (MIN) directly displays the
maximum/minimum (selection of the graph is not required).
• Note that the above operation can be performed on rectangular coordinate (Y=)
and inequality graphs only.

• y-intercepts are the points that 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.
