Which of the relations given by the following sets of ordered pairs is not a function?

select one:
a. {(52)}{(52)}
b. {(−4,−−1,−,,,10)}{(−4,−−1,−,,,10)}< br /> c. {(−8,−−6,−−4,−−2,−−1,−4)}{(−8,−−6,− −4,−−2,−−1,−4)}
d. {(−6,−3,−,,−,3)}

A function will not have any x values the same..they would all have to be different...it does not matter about the y values.
But u are looking for one that is not a function...so u need to look for the one that HAS repeating x values.

Is ur question worded right ? Because...
a. is NOT a function
b. is NOT a function
c. is NOT a function
d. IS a function
