The vertex formula is used to find the vertex of a parabola. There are two ways to find the vertex of a parabola. Vertex, (h, k) = (-b/2a, -D/4a) Where “D” is the discriminant where D = b2 – 4ac. “h” and “k” are the coordinates of the vertex.

To find equation of parabola from the given vertex and a point, we may use vertex form of the parabola. y = a (x - h) 2 + k Here (h, k) is the vertex. To find the value of a, we can apply the

The vertex of the parabola is located at a pair of coordinates which we will call ( h, k ). In order to determine what they are, we can simply use the standard form of the quadratic
