On a remote tropical island, the average life expectancy of women is given by the model
where is the "average life expectancy for a woman" since 1980. Thus, is the number of years since 1980. What is the predicted average life expectancy of a woman in the year 2018?
y=√6000+67x-2.2x^2+.04x^3

Your problem seems to be missing the variables...:(
If you mean
y=√(6000 + 67x - 2.2x^2 + .04x^3)
then since 2018 - 1980 = 38,
y(38) = 86.97
y=√(6000 + 67x - 2.2x^2 + .04x^3)
then since 2018 - 1980 = 38,
y(38) = 86.97
