The population of a certain city was 4,192 in 2002. It is expected to decrease by about 0.38% per year. Write an exponential decay function, and use it to approximate the population in 2022. The exponential decay function where f(x) is the population of the city x years after 2002 is f(x) = 4192(0.9962)*. The approximate population of the city in 2022 will be (Round to the nearest whole number as needed.)
