We used the data to develop the quadratic equation y=0.339x+8.40x-8.36, which models the number of cellular phone subscribers y (in millions) in the year x, where x = 0 represents 1990, x = 2 represents 1992, and so on. Use the model and the table to the right to answer questions (a)-(f) below. (a) What value of x corresponds to 2008? x= (Type an integer.) (b) Use the model to find the number of subscribers in 2008, to the nearest million. million (Round to the nearest integer.) How does the result compare with the actual data in the table? OA. The result is less than the actual number. OB. The result is more than the actual number. OC. Neither. (c) What value of x corresponds to 2010? x= (Type an integer.) (d) Use the model to find the number of subscribers in 2010, to the nearest million. million (Round to the nearest integer.) How does the result compare with the actual data in the table? OA. The result is less than the actual number. B. The result is more than the actual number. OC. Neither. (e) Assuming that the trend in the data continues, what value of x corresponds to 2016? (Type an integer.) x= (f) Use the model to find the number of subscribers in 2016, to the nearest million. million (Round to the nearest integer.) The table shows the number of cellular phone subscribers (in millions) in a particular country. Year Subscribers (in millions) 1990 5 1992 11 1994 24 1996 44 1998 69 2000 109 2002 141 2004 182 2006 233 2008 270 2010 296 2012 326
