The population of a certain city was 25,000 in 2010 and decreased by 4% each year afterwards. The population can be modeled by exponential function of the form y=ab^x, where x represent the number of year since 2010. What are the values of a a and b
Answers: 1
a is the initial value and b is the growth/decay rate. Our initial population was 25,000 so a = 25,000. Our rate of decay is 4% or, as a decimal, .04. BUT if the rate of decay is .04, then .96 remains. b = .96
