Parabolas are graphs with equations of the form where
The vertex of the parabola can provide us with information if parabola has the maximum or the minimum , so we need to be able to find its coordinates.
for any we use the quadratic formula ,which could be written as
then will give us the of the vertex.
We need only to find that coordinate, and then find the that goes with it by using that value for in our equation for .

or
write equation in vertex form:
}
where (,) are the vertex coordinates
