You can put this solution on YOUR website!
If it is 2x^2 +4x-6 (not clear, so I will use that)
\n" ); document.write( "the vertex x-value is -b/2a, where b=4 and a=2
\n" ); document.write( "-4/4=-1 is x
\n" ); document.write( "substitute in and f(-1)=2-4-6=-8
\n" ); document.write( "(-1,-8)
\n" ); document.write( " $\"graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C2x%5E2%2B4x-6%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
