document.write( "Note: vertex form of a Parabola opening up(a>0) or down(a<0),  
\n" );
document.write( "where(h,k) is the vertex  and  x = h  is the Line of Symmetry
\n" );
document.write( "The standard form is , where  the focus is (h,k + p)
\n" );
document.write( " ,  V(0,0), 4p = 12,  p = 3, F(0,3) and directrix is y = -3
