Working Age The projected ratio of the working-age population (25- to 64-year-olds) to the elderly shown in the figure below defines the ratio as a function of the year shown. If this function is defined as y = f ( t ) where t is the year, use the graph to answer the following: a. What is the projected ratio of the working-age population to the elderly population in 2020? b. Estimate f (2005) and write a sentence that explains its meaning. c. What is the domain of this function? d. Is the projected ratio of the working-age population to the elderly increasing or decreasing over the domain shown in the figure?

Solution Summary: The author explains that the projected ratio of the working age population to the elderly population in 2020 is approximately 3 to 1. The domain of a function y=f(x) is the set of all values
