Question

a graph of a quadratic function is shown on the grid which coordinate best represents the vertex of the graphA) (0,9)B) (9,0)C) (0,3)D) (3,0)

Answer 1

Case: Identifying the vertex of the graph

Given: A graph with a turn point

Required: To identify the coordinate of the vertex (or turning point)

Method:

The turning point of the graph is where the graph changes direction (or behaviour)

Final answer:

The vertex of the graph is at (3,0) Option (D)
