Question

Identify the vertex of the graph. Tell whether it is a minimum or maximum.

Answer 1

Given that the graph of the quadratic function.

We need to determine the vertex of the graph and also determine whether it is a minimum or maximum value.

Vertex:

The vertex of the parabola is the point at which the parabola makes a turn to form a U - shaped graph.

Hence, from the figure, the parabola turns at the point (0,-2) to form a U - shaped graph.

Therefore, the vertex of the graph is (0,-2)

Minimum or maximum value:

When the parabola is open upwards, then the vertex is the lowest point on the graph which is the minimum value on the graph.

Thus, the graph has a minimum value.

Hence, the vertex of the graph is (0,-2); minimum value.

Therefore, Option A is the correct answer.
