Based on data for the years 1910-2007, the expected life span of people in Country A can be described by the function f(x) = 10.963 + 14.322 In x, where x is the number of years from 1900 to the person's birth year. (a) Estimate the birth year for which the expected life span is 75 years. (b) Use graphical methods to determine the birth year for which the expected life span is 75 years. Does this agree with the solution in part (a)? (a) The birth year is approximately for which the expected life span is 75 years. (Round to the nearest whole number as needed.)
