You can put this solution on YOUR website!
It's a function as long as you don't have
\n" ); document.write( "2 different values of $\"y\"$ for the same $\"x\"$
\n" ); document.write( "The format is (x,y)
\n" ); document.write( "and the $\"x+\"$ for each point is
\n" ); document.write( "( 0,y[1] ), ( 5,y[2] ), ( 4,y[3] ), ( 3,y[4] )
\n" ); document.write( "None of the x-values are repeated, so with
\n" ); document.write( "just those points given, it is a function.
\n" ); document.write( "If the next point was (4,y[5]), then both
\n" ); document.write( " $\"+y%5B3%5D+\"$ and $\"+y%5B5%5D+\"$ would have the same
\n" ); document.write( "x-value which is $\"+4+\"$ , so then it would no longer
\n" ); document.write( "be a function.
\n" ); document.write( "Hope this helps
