No wrong answerswhich set of ordered pairs is not a function? {(2,3) (3,4) (5,6) (7,8)} {(2,4) (2,6) (3,8) (4,10)} {(1,4) (2,8) (3,12) (4,15)} {(6,10) (5,8) (4,6) (3,4)}

The second set. One input has two outputs and thats not allowed. Best way to think about it is the vertical line test (if you were to plot this and draw lines at each point would it go through one point or more than one? if its more than one its not a function)
