You can put this solution on YOUR website!
First, get the equation in terms of y:\r
\n" ); document.write( "\n" ); document.write( " $\"x+=+-2y%5E2\"$ Divide both sides by -2.
\n" ); document.write( " $\"x%2F-2+=+y%5E2\"$ Now take the square root of both sides.
\n" ); document.write( " $\"y+=+%2Bsqrt%28x%2F-2%29\"$ , $\"y+=+-sqrt%28x%2F-2%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Take a look at the graph:\r
