3. The data in the accompanying table show the growth of cellular phone subscriptions in the U.S. from 1993 to 1999. Year 1993 1995 1996 1997 1999 Subscriptions(millions) 16.00 33.80 44.10 55.30 86.05 a) Fit an exponential curve y = ab* that best fits the data, where x = 0 represents the year 1990 and y is the number of cellular phone subscriber. Approximate a and b to the nearest thousandth. b) Use the model to estimate the number of cellular phone subscriber in 1998.
