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 $f\left(65\right)=0.0069502\left(65{\right)}^{2}-1.6357\left(65\right)+93.76$

$=29.364595-106.3205+93.76$

$\approx 16.8$ years
The life expectancy of a female whose current age is 75 is

$f\left(75\right)=0.0069502\left(75{\right)}^{2}-1.6357\left(75\right)+93.76$

$=39.094875-122.6775+93.76$
