A country's census lists the population of the country as 242 million in 1990, 285 million in 2000, and 322 million in 2010. Fit a second-degree polynomial P(t) = at^2 + bt + c passing through these three points. (Let the year 2000 be x = 0 and let p(x) represent the population in millions.) Sketch the parabola, P(t).
