Explanation Given: The percent of college freshmen who responded that they spent 6 or more hours per week studying during their high school senior year is represented in the below table, The data is represented in terms of the number of years after 1992. Year, x Percent Who Say They Studied 6 or More Hours per Week 1992, 0 43 2002, 10 33 2012, 20 38 Source 2014 Brown Center Report Education, compiled "The American Freshman," UCLA Higher Education Research institute Calculation: Assume a quadratic function to represent the data be f ( x ) = a x 2 + b x + c . From the given table, it is clear that points ( 0 , 43 ) , ( 10 , 33 ) and ( 20 , 38 ) is the solution of quadratic function, that is, To determine (b) To find: The estimated percentage of college freshmen who say they spent 6 or more hours per week studying during their high school senior year in 2007 and in 2014, using the function.
