Question: MALE LIFE EXPECTANCY Suppose the life expectancy of a male at birth in a certain country is described by the function
f(t) = 46.9(1 + 1.09t)0.1 (0 ≤ t ≤ 150)
where t is measured in years, with t = 0 corresponding to the beginning of 1900. How long can a male born at the beginning of 2000 in that country expect to live? What is the rate of change of the life expectancy of a male born in that country at the beginning of 2000?
