Question

A graph of a quadratic function is shown on the grid. 5 3 N 1 | -5 -4 -3 -2 -1 1 2 3 4 5 1 -3 -5 Which coordinates best represent the vertex of the graph? F (2.4,0) G (0, -1) H (-0.4,0) J (1,-2)

Answer 1

The vertex is located at (1, -2) (letter J)

SOLUTION:

The vertex is the minimum/maximum point in the graph. It is the tip of the curve. It is the peak/valley of a curve.
