Suppose that the population of some state in 2010 was P = 35 million and its annual percentage rate of continuous growth is R = 1.06%. (a) Write the formula f(x) = P ex, where r is in decimal notation, that models the population in millions x years after 2010. (b) Estimate the population in 2022. (a) f(x)=(Use integers or decimals for any numbers in the expression.) (b) The population in 2022 will be approximately (Round to the nearest whole number as needed.) million.
