A function is graphed below. The [color=#6aa84f][b]GREEN[/b][/color] points control its shape. The [b][color=#f1c232]YELLOW[/color] [/b]points can be dragged anywhere along the graph. Each [b][color=#f1c232]YELLOW[/color] [/b]point lines up with a [color=#1e84cc][b]BLUE[/b][/color] point, whose height determines the slope of the line segment through the [color=#f1c232][b]YELLOW[/b][/color] point. Move the [b][color=#1e84cc]BLUE[/color][/b] points to make the slopes tangent to the function. Then slide the slider to extend the line segments and graph the true derivatives.
