\n" );
document.write( "f(x)=2x^2-12x+20
\n" );
document.write( "Using the vertex form of a parabola,  where(h,k) is the vertex
\n" );
document.write( "f(x)=2(x^2-6x)+20   |completing square to put into vertex form
\n" );
document.write( "f(x)=2[(x-3)^2 - 9] +20
\n" );
document.write( "f(x) = 2(x-3)^2 -18 + 20
\n" );
document.write( "f(x) = 2(x-3)^2 + 2   |Vertex is Pt(3,2)  Line of symmetry is x= 3
