Raytown Building Parabolas

Topic:
Parabola
Hello students! The purpose of this applet is to familiarize you with the parabola. Your goal is to place the vertex of the parabola in the green circle, and, having accomplished this, to place on leg of the parabola in the red circle. There is text (words that show up) that will alert you to sufficient manipulation of the parameters (when you are close enough, it will let you know). Try this a couple of times.
