**Parabola CliffsNotes**

Parabolas as Conic Sections A parabola is the curve formed by the intersection of a plane and a cone, when the plane is at the same slant as the side of the cone. A parabola can also be defined as the set of all points in a plane which are an equal distance away from a given point (called the focus of the parabola) and a given line (called the directrix of the parabola).... Mar 26, 2012 · Conic Sections, Parabola : Find the Focus and Directrix. In this video, we find the focus and directrix of a parabola. A parabola is a locus of points equidistant from a single point, called the focus of the parabola, and a line, called the directrix of the parabola.

**What's the difference between these two approaches to find**

It's gonna be a parabola with a, with a vertex right here at the origin. So this is the graph, this is the graph, "y is equal to f(x)," this of course is the x-axis, this of course is the y-axis. So let's think about it, what is the set of all possible outputs? Well in this case, the set of all possible outputs is the set of all possible y's here. Well, we see, y can take on any non-negative...

**Focus and Directrix of a Parabola 2 Khan Academy**

A parabola is the set of points in a plane that are the same distance from a given point and a given line in that plane. The given point is called the focus, and the line is called the directrix. The midpoint of the perpendicular segment from the focus to the directrix is called the vertex of the parabola. how to get a little logo for website LICENSE: Creative Commons (Attribution-Noncommercial-No Derivative Works).
