Question

Is this a relation function?
{(14,15)(5,7)(3,10)(11,1)(5,8)}

tbnrfrags · Answer

A relation is not a function if there are 2 "y" values for any given "x" value.  So, if you have multiple "x"'s (first number in each ordered pair), then there is no function.

tbnrfrags · Answer

So, you go through each ordered pair, one by one.  First ask if there are multiple "14".  If yes, then no function.  If not, go to the next ordered pair.  Are there multiple 5's?  If yes, no function.  If not, then go to the third, etc
