in 1992, the life expectancy of males in a certain country was 69.8 years. in 1999, it was 72.4 years. Let E represent the life expectency in year t and let t represent the number of years since 1992.
The linear function E(t) that fits the data is
E(t) =_ t+_
Use the function to predict the life expecteancy of males in 2006.
