Identify extrema on a graph

DRAFT. This applet is under review.[br][br]Drag the points (the colored shapes) from the top of the screen, and place them at the appropriate locations on the graph. [br][list][*]Multiple points may go to the same position on the graph.[/*][*]You must drag points to within 0.5 of the "true" position.[/*][*]There may be more points than you need to move; just leave any unneeded points within the "home region" rectangle at the top of the screen.[/*][/list]When you finish, click the "Check" button to see how you did. Good luck![br][br](One last note. The definition of [b]local[/b] extrema varies from author to author. In this activity, we suppose that an endpoint may be a local extremum.)
