MDetermining Maximums and Minimums Example To determine the maximum and minimum for y=x (x + 2).(x - 2): DEW ED W1' Frial FI FFIallgli g(MAX) (This puts the unitinto standby waiting for selection of a graph.) Y=X+1 ma Specify the graph and determine the maximum. Cal Y=X (X+2) (X - 2) MN H=- I. 1541 Pa. 1:1192014 33 Specify-the graph and determine the minimum.

Y=X+1 V-I[PT Determine the y-intercept. 33 Y=X+ 1 Y-ICPT PI •y-intercepts are the points that the graph intersects the y-axis. •If there is only one graph, pressing Fa (Y-ICP) directlydisplays the y-intercepts (selection of the graph is not required). EDetermining Points of Intersection for Two Graphs Example After drawing the following three graphs, determine the points of intersection for the Graph A and Grabh C. Use the same range parameters as those defined for the examples above: Graph A: y = x + 1 Graph B: y = x (x + 2) (x - 2) Graph C: y = x2 33 I WF FI EMItr7RWIThrrnill FS -189-
