You can put this solution on YOUR website!
$\"2xy+=+1\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%282xy%29%2F%282x%29+=+1%2F%282x%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"y+=+1%2F%282x%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equation $\"y+=+1%2F%282x%29\"$ is a function because we can plug in any x value, but x = 0, and we'll get EXACTLY ONE y value as the output. Visually the graph passes the vertical line test to further prove this is a function. \n" ); document.write( "
