The table gives estimates of the world population, in millions, from 1750 to 2000. (Round your answers to the nearest million.)Year Population1750 7901800 9801850 12601900 16501950 25602000 6080

(a) Use the exponential model and the population figures for 1750 and 1800 to predict the world population in 1900 and 1950. Compare with the actual figures.
(b) Use the exponential model and the population figures for 1850 and 1900 to predict the world population in 1950. Compare with the actual population.
(c) Use the exponential model and the population figures for 1900 and 1950 to predict the world population in 2000. Compare with the actual population and try to explain the discrepancy.
