Answer:
Vertex ( 0,1) and it is maximum.
Explanation:
Given : graph of parabola .
To find : What are the coordinates of the vertex of the graph? Is it a maximum or minimum.
Solution : We have given the graph of parabola
Vertex : the highest point ; the top.
Vertex : ( 0 , 1) because it cut at y ,
When the parabola opens down, the vertex is the highest point on the graph is called the maximum, or max.
Therefore, Vertex ( 0,1) and it is maximum.
