Here’s the explanation of the vertex of the parabola based on the given points:

1.Definition of Vertex: The vertex is the point on a parabola where it changes direction. For parabolas that open downwards, this point represents the maximum value of the graph.

2.Identifying the Vertex from Given Points: The points provided are:

Among these points, (1, 5) has the highest y-coordinate, making it the vertex of the parabola.
