The standard form of a parabola: y=ax2+bx+c, where a0
The vertex is the minimum or maximum point of a parabola. If a>0, the vertex is the minimum point and the parabola opens upward. If a<0, the vertex is the maximum point and the parabola opens downward.
If you want to find a vertex, you need to find the x- and y-coordinates.
The formula for the axis of symmetry and the x-coordinate of the vertex: x=b2a
To find the y-coordinate of the vertex, substitute the value for x into the equation and solve it for y.
y=a(b2a)2+b(b2a)+c

When the axis and the perpendicular tangent at the vertex V(α,β) are parallel to the coordinate axes, the standard form is:
(yβ)2=±4a(xα) or (yα)2=±4a(xβ)

The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x^{2} term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x^{2} term is negative, the vertex will be the highest point on the graph, the top of the "U "-shape.
