The vertex form of a quadratic equation is written like f (x) = a(x - h)2 + k, with the letter h and the letter k being the vertex point of the parabola. It can be used to create an equation when the vertex of the parabo... More »

A vertex form converter is a computer program or a web application that converts between the standard form of a quadratic equation and its vertex form. Because vertex form is easier to visualize and plot than standard fo... More »

Change a quadratic function to its vertex form by applying a process called completing the square, then isolate the y variable on one side of the equation. The vertex form is represented by the formula y = a(x-h)^2 + k, ... More »

The standard form of the equation for a parabola is y = ax^2 + bx + c. A parabola is the set of all points in a plane that are equidistant from a given line and a given point not on the line. More »

The directrix of a parabola refers to a straight line that is drawn perpendicular to the axis of symmetry of a parabola. This line does not touch the parabola at any point. In addition, it is a horizontal line if the axi... More »

A geometric plane can be named as a single letter, written in upper case and in cursive lettering, such as plane Q. A plane can also be named by identifying three separate points on the plane that do not form a straight ... More »

Line symmetry of the alphabet occurs when a portion of a letter mirrors another portion. When the image is folded, the portions line up exactly. The line of the fold is considered the line of symmetry and can be horizont... More »
