In 2012, the population of a city was 6.92 million. The exponential growth rate was 1.28% 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.ew an example Get more help -cha) The exponential growth function is P(t) = where t is in terms of the number of years since 2012 and P(t) is the population in millions.(Type exponential notation with positive exponents.
