A. do some research and find a city that has experienced population growth. determine its population on january 1st of a certain year. write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of exponential growth. describe the variables and numbers that you used in your equation. b. find another city whose population starts larger than the city in part (a), but that during this same time experienced population decline. determine its population for january 1st of the same year you picked for part (a). write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of population decline. describe the variables and numbers that you used in your equation. c. explain the similarities and differences between your equations in (a) and (b). d. during what year will the population of city (a) first exceed that of city (b)? show all of your work and explain your steps. e. during what year will the population of city (a) be at least twice the size of the population of city (b)? show all of your work and explain your steps.
