A country's census lists the population of the country as 256 million in 1990, 288 million in 2000, and 316 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. 2020 million million 2030
