Answer:
You have to find the values of each variable when the other is 0. FOr example, you plug in 0 for y and solve as x and that will be the x-intercept.
Step-by-step explanation:
Answer:
6.219*10^3
Step-by-step explanation:
Considering the vertex of the graph, it is found that the quadratic function that is the best model for the data is given by:

<h3>What is the equation of a quadratic function given it’s vertex?</h3>
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:
