A parabola is the shape of the graph of a quadratic. The second directrix is x = h + \frac {a^ {2}} {c} = \frac {9 \sqrt {5}} {5} x = h + ca2 = 59 5. The focus of a parabola can be calculated by knowing the axis of the parabola, and the vertex of the parabola. Whereas it can be calculated via the parabola equation. Step 1: Identify the given equation and determine orientation of the parabola. Step 1: Use the directrix to determine the orientation of the parabola. and its y-coordinate is y, and by definition, in order Given the values of p, q, and r, we want to find three constants a, h, and k such that the equation of the parabola can be written as. Create your account. I guess it could, if the painting is the parabola, the mirror is the focus, and the viewer is the directrix. Since the vertex of the parabola is halfway between the focus and directrix {eq}\begin{align*} 4p & =-8\\ p & = \frac {-8}{4}\\ \mathbf{p} & = \mathbf{-2}\\ \end{align*} {/eq}. For those who struggle with math, equations can seem like an impossible task. In short, it can be concluded that any point on this curve is at equal distance from: The standard form to represent this curve is the equation for parabola.
