The average salaries $S$ (in thousands of dollars) for football players in the National Football League from 2000 through 2008 can be approximated by the model $S=\sqrt{331,054.5 t+616,774}, 0 \leq t \leq 8$ where $t$ is the year, with $t=0$ corresponding to 2000. (a) Use the table feature of a graphing utility to estimate the average NFL player salary each year from 2000 through 2008 . (b) According to the table, when was the first year that the average salary exceeded $\$ 1.5$ million? (c) Find the answer to part (b) algebraically. (d) Use the graphing utility to graph the model and find the answer to part (b).
