Question

look at this graph:
graph of a parabola opening downward with vertex at (0, 0) on a coordinate plane with x-axis from -10 to 10 and y-axis from -10 to 10
what is the maximum value of this function?

Explanation:

Step1: Identify the vertex

The graph is a parabola opening downward, so the vertex is the maximum point. The vertex is at (0, 0) as it's on the y - axis and the highest point of the parabola.

Step2: Determine the maximum value

The y - coordinate of the vertex of a function gives the maximum (for a downward - opening parabola) or minimum (for an upward - opening parabola) value of the function. Since the vertex is at (0, 0), the y - coordinate is 0.

Answer:

0
