Question

look at this graph:
what are the coordinates of the vertex?
( , )

Explanation:

Step1: Identify vertex on graph

The vertex is the highest point of the downward-opening parabola, located at the intersection of the y-axis and the peak of the curve.

Step2: Read coordinates

The x-coordinate is 0 (lies on the y-axis), and the y-coordinate is 4 (aligns with the grid mark for 4 on the y-axis).

Answer:

$(0, 4)$
