A parabola is a set of points formula in the plane that are equidistant from a given line called the directrix , a given point not on the directrix called the focus. Vertex Form of Parabolas Worksheets. The parabola is the curve formed from all the points ( x formula y) that are equidistant from the directrix the focus. The focus does not lie on the directrix. Therefore the focus is on y- axis in the negative direction parabola opens downwards. The point of the parabola lying halfway between the focus and the directrix is called the vertex. So in formula this case the directrix will be the line x = - 1 – 2, x = - 3.

Focus formula

A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix. Given the focus and the directrix of a parabola, find its equation. Topic: Parabola Find the Focus and Directrix - Worksheet 4 Find the Focus and Directrix 1. - x = ( 1/ 8) y2 3.
