Solve the problem.The table shows the number of new cases (in thousands) of a certain disease diagnosed in a country in various years. 
Let n = f(t) be the number of new cases (in thousands) of the disease diagnosed at t years since 2010. Suppose that you wish to model f using a quadratic equation. What is the vertex of the model? What does it mean in this situation?
A. (7, 45.7); the largest number of new cases diagnosed was 45,700 in the year 2017 B. (0, 49.4); the largest number of new cases diagnosed was 49,400 in the year 2010 C. (3, 39.3); the smallest number of new cases diagnosed was 39,300 in the year 2013 D. (0, 39.3); the smallest number of new cases diagnosed was 39,300 in the year 2013
