In 2012, the population of a city was 6.66 million. The exponential growth rate was 3.16% 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 11 million? d) Find the doubling time. where t is in terms of the number of years a) The exponential growth function is P(t) = since 2012 and P(t) is the population in millions. (Type exponential notation with positive exponents. Do not simplify. Use integers or decimals for any numbers in the equation.) b) The population of the city in 2018 is (Round to one decimal place as needed.) million. c) The population of the city will be 11 million in about years after 2012. (Round to one decimal place as needed.) d) The doubling time is about years. (Simplify your answer. Round to one decimal place as needed.)
