Cost of Public Colleges The average cost, in dollars, for tuition and fees for in-state students at four-year public colleges over the period 2000–2014 can be modeled by the equation

y = 4.065x² + 370.1x + 3450

where x = 0 corresponds to 2000, x = 1 corresponds to 2001, and so on. Based on this model, for what year after 2000 was the average cost $8605? (Source: The College Board, Annual Survey of Colleges.)
