A country's census lists the population of the country
as 239 million in 1990, 281 million in 2000,
and 319 million in 2010. Fit a second-degree polynomial
passing through these three points. (Let the year 2000 be
x = 0
and let p(x) represent the
population in millions.)
p(x) =
million
Use this polynomial to predict the populations in 2020 and in
2030.
