(Modeling)Airline Passenger Growth  The number of fliers on 10- to 30-seat commuter aircraft was 1.4 million in 1975 and 3.1 million in 1994. It is estimated that there were 9.3 million fliers in the year 2006. Here are three possible models for these data, where x = 0 corresponds to the year 1975.

A. y = .24x + .6

B. y = .0138x2 − .172x + 1.4

C. y = .0125x2 − .193x + 1.4
