    If you mean one-to-one function then

    for every input, you get one output

    (x, y)

    x=input

    y=output

    basically, x never repeats witha differnt y

    look at them

    1st one

    not since we have (1,5) and (1,-3) the 1 repeats with 2 y's

    2nd one

    yes, no repeats

    3rd one

    not since (-2,-5) and (-2,9), - 2 repeats with - 5 and 9

    4th one

    not since we have (-3,1) (-3,2), (-3,-3) - 3 repeats with 1,2,-3

    answer is 2nd one or

    { (3,-1), (7,1), (-6,-1), (9,1), (2,-1) }
