Chapter 4.3, Problem 92E

Male life expectancy. The life expectancy for males born during $1980\text{-}1985$ was approximately $70.7$ years. This grew to $71.1$ years during $1985\text{-}1990$ and to $71.8$ years during $1990\text{-}1995$. Construct a model for this data by finding a quadratic equation whose graph passes through the points $\left(0,70.7\right),\left(5,71.1\right)\text{ and }\left(10,71.8\right)$. Use this model to estimate the life expectancy far males born between $1995\text{ and }000$ and for those born between $2000\text{ and }2005$.
