You can put this solution on YOUR website!
Graph it:\r
\n" ); document.write( "\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cx%5E2-9%29\"\r
\n" ); document.write( "\n" ); document.write( "The graph has a minimum at (0,-9). We know this is a minimum because the graph curves up and goes on to infinity.
\n" ); document.write( "
\n" );
