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

Best ResponseYou've already chosen the best response.0so 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.

Best ResponseYou've already chosen the best response.1no, 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
