You can put this solution on YOUR website!
A relation is nothing more than a set of ordered pairs.
\n" ); document.write( "

\n" ); document.write( "A function is a set of ordered pairs with unique ( non-repeating ) X or Input Values.
\n" ); document.write( "

\n" ); document.write( "So to solve this question make a list of ordered pairs using your arrows, the ordered pairs are
\n" ); document.write( "

\n" ); document.write( "(3, -1), (3, -5), (2, -5), (5, 5), (4, 6)
\n" ); document.write( "

\n" ); document.write( "Now to tell weather this is a function or not, look at JUST the X values, if any of those X values repeat, that Relation is NOT a function, so since there are two 3's in the first and second ordered pair, that relation is NOT a function.
\n" ); document.write( "
\n" );
