The bar graph shows the population of the United States, in millions, for six selected years.
Source: U.S. Census Bureau
Here are two functions that model the data:
a. Write a function that models the total U.S. population, P(x) in millions, x years after 1985.
b. Write a rational function that models the fraction of men in the U.S. population, R(x), x years after 1985.
c. What is the equation of the horizontal asymptote associated with the function in part (b)? Round to two decimal places. What does this mean about the percentage of men in the U.S. population over time?
