0n a remote tropical island, the average life expectancy of women is given by the model y= \sqrt(6000+67x-2.2x^2+.04x^3) , where y is the "average life expectancy for a woman" since 1980. Thus, x is the number of years after 1980. What is the predicted average life expectancy of a woman in the year 2007?
