Answer

Explanation:

Step1: Analyze the parabola's direction

The parabola opens downward (since it has a peak), so the vertex is a maximum point.

Step2: Identify the vertex coordinates

From the graph (and the options), the vertex with a maximum (since parabola opens down) has coordinates ((-2, 2)) (option D) or check the options: Option D says Vertex: ((-2,2)) and Maximum, which matches a downward - opening parabola (vertex is the highest point, so maximum). Options A and B have vertex ((-2,-2)) which would be a minimum if parabola opened up, but here it opens down. Option C has vertex ((2,-2)) and minimum, which is incorrect for this graph.

Answer:

D. Vertex: ((-2,2)) Maximum
