(Modeling) U.S. Airline Passengers The num- ber of fliers on scheduled flights of U.S. airline companies was approximately 548million in 1995, 739million in 2005, and 704million in 2009. (Source: Air Transport A ssociation of A merica.) Here are three possible models for these data, where \( x = 0 \) corresponds to the year \( 1995 \) . A. \( y = 12.68 x + 562.0 \) 

B. \( y = - 1.983 x ^ { 2 } + 38.91 x + 547.8 \) 

C. \( y = - 1.632 x ^ { 2 } + 34.56 x + 544.5 \) 

The table shows each equation evaluated at the years 1995,2004, and 2009 . Decide which equation most closely models the data for these years.
