Watch the video and then solve the problem given below. + Projected Click here to watch the video. Population (millions) a. In 2000, the population of a country was approximately 6.25 million and by 2015 it is projected to grow to 7 million. Use the exponential growth model A = Age , in which t is the number of years after 2000 and A is in millions, to find an exponential growth function that models the data. Year b. By which year will the population be 9 million? . . . a. The exponential growth function that models the data is A = (Simplify your answer. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) b. The country's population will be 9 million in the year
