[color=#c51414][b]Directions:[/b][/color][br][br]1) [color=#0a971e]Note the sine function displayed in green in the upper right hand corner of the applet.[/color][br]2) Move each of the [color=#c51414]5 red points[/color] up and/or down so that the [color=#c51414]red wave that passes through these 5 points is the EXACT GRAPH[/color] of the [color=#0a971e]green equation[/color] displayed.[br] (There may be times when the red graph will disappear--and that's okay. It'll reappear as you continue to move these points.) [br]3) Once you graph the displayed function correctly, the entire graph will turn green and a "NICE JOB !!!" box will appear.[br]4) Click on the "Generate New Function to Graph" to display a new equation.[br]5) Repeat steps (1) - (3). Then repeat step (4). [br]6) [b]Complete this activity as many times as you need in order to master this concept!
