In​ 2012, the population of a city was million. The exponential growth rate was 2.72​% per year. ​a) Find the exponential growth function.
​b) Estimate the population of the city in 2018.
​c) When will the population of the city be 10 ​million?
​d) Find the doubling time.
​a) The exponential growth function is ​P(t)
nothing​, where t is in terms of the number of years since 2012 and​ P(t) is the population in millions.
