Considering the vertex of the graph, it is found that the quadratic function that is the best model for the data is given by:
The equation of a quadratic function, of vertex (h,k), is given by:
In which a is the leading coefficient.
Researching the problem on the internet, it is found that the vertex is at point (4,800), hence h = 4 and k = 800.
It has a value of y = 0 at x = 6, hence:
Thus, the model is:
