Question

look at this graph: 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 the origin \((0,0)\).

Step2: Determine the maximum value

The \(y\)-coordinate of the vertex gives the maximum value of the function. For the point \((0,0)\), the \(y\)-value is \(0\).

Answer:

\(0\)
