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

Explanation:

Step1: Identify the vertex of the parabola

The vertex of a parabola (y = ax^{2}+bx + c) (for (a\neq0)) gives the maximum or minimum value. For a parabola opening downwards ((a<0)), the vertex is the maximum - point. In the given graph, the vertex is at the point ((0,0))

Step2: Determine the (y) - coordinate of the vertex

The (y) - coordinate of the vertex of a function (y = f(x)) gives the maximum (if the parabola opens downwards) or minimum (if the parabola opens upwards) value of the function. Since the vertex is ((0,0)), the (y) - coordinate is (0)

Answer:

(0)
