In 1994, the National Football League introduced a salary cap that limits the amount of money spent on players’ salaries. The quadratic model

y = 0.2313x² + 2.600x + 35.17

approximates this cap in millions of dollars for the years 1994–2009, where x = 0 represents 1994, x = 1 represents 1995, and so on. (Source: www.businessinsider.com)

(a) Approximate the NFL salary cap in 2007 to the nearest tenth of a million dollars.

(b) According to the model, in what year did the salary cap reach 90 million dollars?
