You can put this solution on YOUR website!
that is (x+3)^2
\n" ); document.write( "so x=-3
\n" ); document.write( "Set it to equal y
\n" ); document.write( "(x+3)^2=y
\n" ); document.write( "with the vertex at -3, 0
\n" ); document.write( "the low point is at -3,0
\n" ); document.write( "it curves up like a bowl.
