Using the given function for life expectancy of female whose current age is x years old, the life expectancy of a female whose curreny age is 65 is f(65)=0.0069502(65)2−1.6357(65)+93.76=29.364595−106.3205+93.76  ∼16.8years The life expectancy of a female whose current age is 75 is f(75)=0.0069502(75)2−1.6357(75)+93.76=39.094875−122.6775+93.76   ∼10.2years

Life expectancy for x=65 is:  f(65)=0.0069502(65)2−1.6357(65)+93.76  =0.0069502(4225)−1.6357(65)+93.76  =29.364595−106.3205=93.76  =16.8 years  Life expectancy for x=75 is:  f(75)=0.0069502(75)2−1.6357(75)+93.76  =0.0069502(5625)−1.6357(75)+93.76  =39.094875−122.6775+93.76  =10.18 years  16.8 years for male who is 65 years old and 10.18 years for a male aged 75 years
