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 standard form of a quadratic equation is y = ax^2 + bx + c, so you may need to move terms around to make the equation take this form. A quadratic equation might be written in the vertex form, which is y = a(x - h)^2)... More »

To find the vertex of a parabola, put the terms of the standard parabola equation into vertex form. The standard equation is y = ax^2 + bx + c. The vertex form is y = a(x - h)^2 + k. The vertex of the parabola is at poin... More »

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 »
