Question

using the graph, determine the coordinates of the vertex of the parabola.

Explanation:

Step1: Identify the parabola's vertex

The vertex is the lowest point (minimum) of the upward-opening parabola. Locate this point on the graph.

Step2: Read coordinates from axes

The vertex lies at $x=1$ and $y=-9$, so its coordinates are $(1, -9)$.

Answer:

$(1, -9)$
