You can put this solution on YOUR website!
The \"vertex form\" is:
\n" ); document.write( "y = a(x-h)^2 + k
\n" ); document.write( ".
\n" ); document.write( "Your equation:
\n" ); document.write( "f(x)=-3x^2
\n" ); document.write( "is already IN vertex form:
\n" ); document.write( "f(x)=-3x^2
\n" ); document.write( "is essentially:
\n" ); document.write( "f(x)=-3(x-0)^2 }+ 0
\n" ); document.write( "So, the vertex is at (h,k) or (0,0) \n" ); document.write( "

\n" );
