The co-ordinate of vertex is

#### Explanation:

The general form of Parabola is

So here

We know the x co-ordinate of the vertex is

Therefore the x co-ordinate of the vertex is

Since the parabola passes through vertex the y co-ordinate will satisfy the above equation. Now putting

Thus the co-ordinate of vertex is
