Answer 1

The variable "y" represents the population of Bentonville after a certain number of years (x) since 2000. The initial population in 2000 is 20,308. The growth rate is represented by 0.0507, which means that the population increases by 5.07% each year. The exponent "x" represents the number of years since 2000.
