Use a calculator with a key or a A key to solve the following: The exponential function f(x) = 565(1.026)* models the population of a country, f(x), in millions, x years after 1968. Complete parts (a)-(e). a. Substitute 0 for x and, without using a calculator, find the country's population in 1968. The country's population in 1968 was 565 million. b. Substitute 27 for x and use your calculator to find the country's population, to the nearest million, in the year 1995 as modeled by this function. The country's population in 1995 was 1130 million. c. Find the country's population, to the nearest million, in the year 2022 as predicted by this unction. The country's population in 2022 will be 2259 million. d. Find the country's population, to the nearest million, in the year 2049 as predicted by this function. The country's population in 2049 will be million.
