Posted by Shannon on Tuesday, December 7, 2010 at 8:43pm.

My problem:
From 1992 to 1996, the annual income for all the private golf courses in the United States can be approximated by the model: I=59t^2+2254, where I is the annual income in millions of dollars and t is the year, with t=0 corresponding to 1990.
1. In which year did the annual income increase to more than $3,000,000?
2. In which year did the annual income increase to more than $4,000,000?
3. Predict the year in which the annual income will increase to more than $5,500,000.
4. In which year was the annual income $2,254,000?
