Solve the problem.The accompanying graph shows the average number of degrees above/below normal in December from 2000 - 2009 where x = 0 represents 2000. 
Construct a polynomial of minimum degree that models the graph.
A. y = - 
x(x - 2)(x - 6)(x - 9)
B. y = 
(x - 2)(x - 6)(x - 9)
C. y = 
x(x - 2)(x - 6)(x - 9)
D. y = 
x(x + 2)(x + 6)(x + 9)
