The bar graph shows the percentage of people 25 years of age and older who were college graduates in the United States for eight selected years. The functions f ( x ) = 6.43 ( 1.027 ) x and g ( x ) = 40.9 1 + 6.6 e − 0.049 x model the percentage of college graduates, among people ages 25 and older; f ( x ) or g ( x ) , x years after 1950. Use these functions to solve Exercises 75–76. 75. Which function is a better model for the percentage who were college graduates in 2014?
