It is the shape of the height versus time graph of a ball tossed straight in the air.
This shape is traced out by the set of all points that are equidistant from a focus and a directrix ("dir- ECK-tricks"). It is the only conic section that can be graphed as a function. It is the shape of the height versus time graph of a ball tossed straight in the air. For 10 points, identify this shape that is traced out by the graph of any quadratic function.
