Use a calculator with a Ly" key or a | | key to solve the following The exponential function ((x) =575(1 026)" models the population of a country, ((x), in millions, x years after 1973. Complete parts (a) -(e) imp a. Substitute 0 for x and, without using a calculator, find the country's population in 1973 T of The country's population in 1973 was million b. Substitute 27 for x and use your calculator to find the country's population, to the nearest million, in the year 2000 as modeled by this function 1 of The country's population in 2000 was million T of 1 c. Find the country's population, to the nearest million, in the year 2027 as predicted by this function The country's population in 2027 will be million Doff d. Find the country's population, to the nearest million, in the year 2054 as predicted by this function The country's population in 2054 will be million 1 of 1 e. What appears to be happening to the country's population every 27 years? 1 of 2 O A. It appears that the population is decreasing by a factor of every 27 years O B. There does not appear to be a pattern 0 of 1 O C. It appears that the population is growing by a factor of 3 every 27 years on It appears that the bobulation is arowing by a factor of 2 every 27 vears
