Question

1. What are the coordinates of the vertex of the graph? Is it a maximum or minimum?

Answer 1

Hi there!

The correct answer is: (0,1) maximum

Explanation:

vertex: the point where the parabola crosses its axis of symmetry.

when the graph is concave down, maximum

when the graph is concave up, minimum

Answer 2

Coordinates of the vertex: (0, 1), and it is a maximum.

this corresponds to the second of the listed answer options.

Explanation:

Notice that the vertex of the parabola is at the very top of the curve, and corresponds to the maximum value that the coordinate "y" can reach for the parabola (y = 1)

The position of that vertex is exactly at the point where x = 0 and y = 1, so this can be written as:

(0, 1)
