The population of a certain city was 4001 in 1999. It is expected to decrease by about 0.37% per year. Write an exponential decay function, and use it to approximate the population in 2027

An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036

Exponential equation

The standard exponential function is expressed as:

P(t) = P0e^-rt

  • P0 is the initial population = 4001
  • r is the rate. = 0.37% = 0.0037
  • t is the time

Substitute

P(t) = 4001e^-(0.0037)t

If t = 28 (by 2027)

An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036
