Use a system of equations to solve problem.The following table shows the number of dog collars, in thousands, produced by Allied Pet Products in the 3 years considered. Number of dog collars
Find a function of the form f(x) = ax2 + bx + c that fits this data. Then, using this function, what would you predict the dog collar production of Allied Pet Products to be in 2007?
A. f(x) = 100x2 - 1600x + 40,000;
82,000 collars
B. f(x) = 100x2 - 1600x + 20,000;
62,000 collars
C. f(x) = 100x2 - 1600x - 20,000;
22,000 collars
D. f(x) = 100x2 - 1600x + 35,000;
77,000 collars
