The population of a country in selected years can be approximated by the following table. Use the given information to answer parts a through c.
Year
1997
Population (millions) 147.0 141.2 140.6 138.2 137.6 134.6
1996
1998 2001
2007
2010
2012
133.7
a. Let 1996 correspond to t=0. Let b be the ratio between the population of the country in 1997 and 1996. Determine an exponential function of the form y = a •b' to
represent the population of the country symbolically. Round to 3 decimal places.
(Type an equation using P as the variable. Type your answer using exponential notation.)
