If the axis of symmetry is {eq}x- {/eq} axis, then the directrix of the parabola with the focus {eq}a {/eq}, and the vertex {eq}(h,k) {/eq} is, {eq}x=h \pm a {/eq}. Similarly, for {eq}y- {/eq} axis, the directri
Directrix: y = k-1/4ay = 2 - 1/12 ⇒ y - 23/12 = 0Derivation of Parabola Equation Let us consider a point P with coordinates (x, y) on the parabola. As per the definition of a parabola, the distance of this point from the focus F is equal to the distance of this point ...
Vertex, Focus, and Directrix of a Parabola Important components of a parabola include the vertex, focus, axis of symmetry, latus rectum, and directrix. See Figure 1 for a diagram of these traits. The,, of adescribes how much the shape differs from a circle. The eccentricity of a parabola...
A latus rectum is a straight line passing through the focus of the parabola and is perpendicular to the axis of the parabola. The latus rectum of the parabola is the focal chord which is parallel to the directrix of a parabola. The prabola has only one latus rectum, but the ellipse and...
What is the center of a parabola called? The point which bisects every chord of the conic passing through itis called the Centre of the parabola. i.e. the origin is the vertex of the parabola. The fixed line is known as Directrix. A chord passing through the focus is known as focal ...

Parabola Equation The equation of a vertical parabola is often seen in vertex form, or y=a(x−h)2+k. In this form, the vertex is at (h, k) and the focus is at (h, k + 14a). Notice that the x-coordinate is the same for both the vertex and focus. So, when working with ...
