Which of the following sets of ordered pairs in the form (x, y) represent a function of x? 3 points {(2,4), (-2,4), (5,3), (7,4)} {(3,,,2), (-6,2)} {(9,2), (-3,4), (-3,1), (7,-4)} {(5,,-,-4), (6,1) show work

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %
