In 1990 th elife expectancy of males in a certain country was 62.6 years. In 1996 it was 65.9 years. Let E represent the life expectancy in a year t and let t represent the number of years since 1990. The linear function E(t) that fits the data is E(t) = t +

use the function to predict life expectancy of males in 2006

1. It will be of the form E = 62.6 + C*t
where C is a constant. Use the fact that E = 65.9 when t = 6 to evaluate the constant.

Then plug t = 16 into your formula to get the life expectancy in 2006, assuming the linear relationship remains valid.

I hope that you understand these directions and can finish the problem yourself.
