What is the vertex of the parabola

The vertex of a parabola is the point where the parabola changes direction. It is the highest or lowest point on the curve, depending on whether the parabola opens upwards or downwards.

The vertex of a parabola with equation y = ax^2 + bx + c can be found using the formula:
Vertex = (-b/2a, f(-b/2a))

Where f(x) = ax^2 + bx + c.
