The population of Detroit has been declining since 1980. According to the 1980 census, this city's population was 1,200,000. By 1993, this population was 1 million.
a) Assuming that the decline is exponential, determine an equation that models Detroit's population since the year 1980. use x=0 for 1980. (Hint: there are two known points on the graph of this exponential: (0, 1,200,000) and (13, 100,000,000)).
b) If the decline has continued at the same rate, what is the population of Detroit predicted by this model in 2002, 22 years after the 1980 census?
