You can put this solution on YOUR website!
Based on $\"y=x%5E2\"$ so vertex minimum. The vertex occurs in the exact middle of the x-axis intercepts, but does not occur on the axis. \r

\n" ); document.write( " $\"y=%28x%2Bb%2F2%29%5E2%2Bc-b%5E2%2F4\"$
\n" ); document.write( "This general form indicates that vertex is ( -b/2, c-b^2/4 );\r
