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 »

Examples of vertical angles in real life settings include the black and white railroad crossing signs found on roadways near railroads, open scissors and the letter "X." Other examples include the point where ceiling bea... 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 »
