Elderly men in the workforce Using data from 1920 and projected to 2030, the percent P of men 65 years of age or older in the labor force can be modeled by
where x is the number of years past 1900 (Source: U.S. Census Bureau).
(a) What *-min and *-max should you use to view this graph for values representing 1900 to 2030?
(b) If P-min = 0, use a table to determine a value for P-max that would show a complete graph of the model.
(c) Graph this equation.
(d) Write a sentence that describes the percent of men 65 years of age or older in the workforce.
