The number of college students in the United States is increasing. The polynomial function f 1x2 = 22x2 + 274x + 15,628 models the number of students enrolled in American colleges for the years 20002010, where x is the years after 2000 and f(x) is the number of college students (in thousands). Write an equivalent expression for f(x) by factoring the greatest common factor from the terms of f(x). (Source: U.S. Department of Education)
