    i don't know how else to say it if there are repeats in the first coordinates, like say \((2,3),(2,7)\) then NO, not a function if all the first numbers are different, i.e if there are no repeats, then YES a function

    do you see any repeated numbers in the first coordinates here \[ A = \{(3, −5), (4, 6), (−3, 9), (2, 7)\}\] or are all the first numbers different?
