One of the common forms for quadratic functions is called vertex form, because it highlights the coordinates of the vertex of the function's graph.
The standard form of a quadratic equation is ax 2 + bx + c. The vertex form of a quadratic equation is. a (x - h) 2 + k. where a is a constant that tells us whether the parabola opens upwards or downwards, and (h, k) is the location of the vertex of the parabola.
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".

What Is Vertex Form? While the standard quadratic form is a x 2 + b x + c = y, the vertex form of a quadratic equation is y = a ( x − h) 2 + k. In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you whether the parabola is facing up ( + a) or down ( − a ).
Vertex form is a form of a quadratic equation that displays the x and y values of the vertex. f(x)= a(x-h)^2+k. You only need to look at the equation in order to find the vertex.
The graph of this equation is a parabola that opens upward. It is translated 2 units to the left and 3 units upward. This is the advantage of vertex form. The transformations required to draw the graph of the function are easy to spot when the equation is written in vertex form.
What is the Vertex Form of a Quadratic Equation? Vertex Form. #y=a (x-h)^2+k#, where # (h,k)# is the vertex.

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". If a is negative, then the graph opens downwards like an upside down "U".
