The vertex form of a quadratic function is given by f ( x ) = a ( x - h ) 2 + k , where ( h, k ) is the vertex of the parabola. Remember: the "vertex? is the "turning point".

Use this vertex form calculator to find how to derive the vertex of a quadratic equation along with a graphical representation. You can convert a quadratic equation from its standard form (ax² + bx + c) to vertex form (a(x-h)² + k) , or vice versa.

In the vertex form, (h, k) represents the vertex of the parabola where the parabola has either maximum/minimum value. If a > 0, the parabola has the minimum value at (h, k) and if a < 0, the parabola has the maximum value at (h, k).

Learn about vertex form in quadratic functions and equations with Khan Academy's introductory video.

This is something that we cannot immediately read from the standard form of a quadratic equation. Vertex form can be useful for solving quadratic equations, graphing quadratic functions, and more. The following are two examples of quadratic equations written in vertex form: 2(x - 7) 2 + 3; vertex at (7, 3) 2(x + 7) 2 - 3; vertex at (-7 , -3)

The vertex form of a parabola's equation is generally expressed as: $ y = a(x-h)^2 +k $ (h,k) is the vertex as you can see in the picture below If a is positive then the parabola opens upwards like a regular "U".
