Vertex Formula

At a point where the curve changes its path is known as the vertex of that curve. In simple word, the curve transforms its path at the lowest or highest point on the curve - these points are called the vertex of the curve.

The vertex of a curve is denoted as (h,k). Let the general form of a quadratic function of the curve is given as, y = ax2 + bx + c. This equation in the vertex form can be written as y = a(x - h)2 + k.

The Vertex Formula is given as,

Vertex = (h,k) = $(\frac{-b}{2a},c-\frac{b^2}{4a})$
