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 OB 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 Subscribers in millions 5 11 24 44 Year 1990 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 69 109 141 182 233 270 296 326
