Question

Which set of ordered pairs does not represent a function?

O{(-1,0),(-5, -8), (6,6), (5,-2)}
o {(5, -7), (-9,-2), (1, -2), (-8,9)}
O {(9,5), (4,5), (6,-9), (-7,-2)}
o {(0, -3), (-5, -9), (8,-6), (0, -2)}

Answer 1

The last one does not represent a function because for it to be a function none of the x’s can repeat and in the last one the 0 repeats.
