Parabolas in Conic Section Form

Below is a graphed parabola. Use the slider to manipulate the constant p in the equation. 1. How does increasing p change the parabola and directrix? 2. How does decreasing p change the parabola and directrix? 3. What do negative values of p do to the parabola and directrix? Parabola Parent Equation: 4p(y-k) = (x-h)2 *In the graph below, the vertex is positioned at (0,0,).
