Below is a graphed parabola. Use the slider to manipulate the constant [b]p[/b] in the equation. [br][br]1. How does [b]increasing p[/b] change the parabola and directrix?[br]2. How does [b]decreasing p[/b] change the parabola and directrix?[br]3. What do [b]negative values of p[/b] do to the parabola and directrix?[br][br]Parabola Parent Equation: 4p(y-k) = (x-h)[sup]2[br][/sup][size=50][size=85]*In the graph below, the vertex is positioned at (0,0,).[/size][/size]
