A country's census lists the population of the country as 260 million in 1990, 283 million in 2000, and 300 million in 2010. Fit a second-degree polynomial passing through these three points. (Let the year 2000 be x = 0, the year 2020 be x = 20, and let p(x) represent the population in millions.) P(x) = million Use this polynomial to predict the populations in 2020 and in 2030. million 2020 2030 million
