Question

look at this graph: what is the maximum value of this function?

Explanation:

Step1: Identify the vertex of the parabola

The vertex of a parabola (for a quadratic function \(y = ax^{2}+bx + c\), \(a
eq0\)) gives the maximum (if \(a<0\)) or minimum (if \(a > 0\)) value. In the graph, the vertex is the highest point.

Step2: Read the \(y\) - coordinate of the vertex

Looking at the graph, the \(y\) - coordinate of the vertex (the highest point of the parabola) is \(8\).

Answer:

\(8\)
