Answer:

B) Vertex (1,2), maximum

Explanation:

First, determine if the graph has a maximum or a minimum value. Since the graph opens downwards, it has a maximum value.

The maximum is the point that has the greatest y value. We can see that the greatest y value is at
y=2. Going down two units from that spot, we can see that the x value is at
x=1. We can plug those into the vertex form,
(x,y). By plugging in we get the point
(1,2).
