Question

a graph of a quadratic function is shown on the grid. which coordinates best represent the vertex of the graph? (0, -1) (-0.4, 0)

Explanation:

Step1: Identify vertex on graph

The vertex of a parabola (graph of quadratic function) is the lowest or highest point. In a parabola opening upwards like this one, it's the lowest point.

Step2: Read coordinates

Looking at the grid, the lowest point is at \(x = 1\) and \(y=-2\).

Answer:

\((1,-2)\)
