The vertex is the minimum or the maximum point of the parabola.
<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

The standard form of a parabola is
The x coordinate of the parabola is calculated using:
The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:
At the end of the calculation,
x and f(x) represent the horizontal and the vertical coordinates of the vertex.
Take for instance:
The x-coordinate of the vertex is:
The y-coordinate is:
So, the vertex of is (-1,11)
