You can put this solution on YOUR website!
find the coordinates of the vertex. and then sketch the graph...
\n" ); document.write( "the problem is:
\n" ); document.write( "y=x^2+6x+12
\n" ); document.write( "You have a quadratic with a=1, b=6
\n" ); document.write( "The vertex is at x=-b/2a=-6/2=-3
\n" ); document.write( "The y value when x=-3 is (-3)^2+6*(-3)+12 = 3
\n" ); document.write( "The vertex is at (-3,3)
\n" ); document.write( "------------------------
