In a parabola, the vertex is located at the maximum or minimum point of the curve.
Since the given parabola opens downwards, it has a maximum point.
Looking at the graph, the x-coordinate of the maximum point is 50 and the y-coordinate of the maximum point is 700.
Therefore the vertex is located at (50, 700).
