Which of the sets of ordered pairs represents a function? A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3), (−9, 5)} Only A Only B Both A and B Neither A nor B

    you have a function when there is only one y-value for a given x-value only one output for any one input

    so if you look at the coordinate sets, a function is either linear or nonlinear. Non linear functions will never have two points lieing in a straight line it will always be offset even by a decimal point. In those two coordinate sets there is a pair that lie on the same line while the others do not... that is not a function.

    no, it would be neither A nor B A cannot be a function because input 8 has 2 outputs -5 and 7 B cannot be a function because input 7 has 2 outputs -4 and -2

    read my definition again in order to be a function you cannot have 2 outputs for the same input
