The vertex of the graph is at minimum or maximum option (D) (1, -1); the minimum is correct.
What is a parabola?
It is defined as the graph of a quadratic function that has something bowl-shaped.
We have shown a graph of a parabola in the picture.
As the graph opens up and has a vertex at (1, -1)
The minimum value of graph,
At x = 1
y = -1
Thus, the vertex of the graph is at minimum or maximum option (D) (1, -1); the minimum is correct.
