Solve the problem.The following table shows the bumping rate per 10, 000 passengers for Airline X from 1994 through 1998. Use regression to find a quadratic function b(x) that can be used to predict the bumping rate x years after 1994. (Round decimals to four places.)
A. b(x) = 0.1235x2 - 0.6927x + 1.7109 B. b(x) = -0.1664x2 - 0.6927x + 1.2109 C. b(x) = 0.1664x2 - 0.6927x + 1.7109 D. b(x) = 0.1235x2 - 0.6535x + 1.2109
