A parabola is a locus of points equidistant from both 1) a single point, called the focus of the parabola, and 2) a line, called the directrix of the parabola. What is the Focus and Directrix? The red point in the pictures below is the focus of the parabola and the red line is ...
Steps to Find the Focus & Directrix of a Parabola Step 1:Identify the given equation and determine orientation of the parabola. Step 2:Find {eq}h, k {/eq}, and {eq}p {/eq} using the equation of the parabola {eq}{(x-h)}^2=4p(y-k) {/eq} or {eq}{(y-k)}^2=4p(x-h)...
The parabola is a figure in which there exist a particular line known as the directrix of the parabola from which all the points on the parabola at equal distance. That equation is known as the directrix and it's given by y=k−p Answer and Explana...
