So, you have this....

-470001t(squared)+4110992t+14032612/-469.4t(squared)+3745t+19774 (sorry don't know how to square them)

and then it asks..Find the year in which the average benefit was $800.00

In order to graph this on my calculator i have to put certain numbers in the "Window" button, and i just can't figure out what numbers to put in...

-Thanks
