Answer:
The coordinates are x=2 and y=16, or (2, 16)
Step-by-step explanation: The definition of the vertex of a parabola(the shown graph) is the highest or lowest point on the graph, depending which way the graph opens. When a graph opens upwards, towards positive y, the vertex is the lowest point. On the contrary, when the graph opens downwards, like this graph, the vertex is the highest point. On the graph, you can see clearly that the highest point on the graph has an x-value of 2 and a y-value of 16, making the vertex (2, 16)
