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

Step-by-step explanation:

In 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

step-by-step explanation:

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20
