document.write( "Using the vertex form of a parabola,  where(h,k) is the vertex
\n" );
document.write( "f(x) = 3x^2-18x+11    |completing the square to put into vertex form
\n" );
document.write( "f(x) = 3(x^2-6)+11
\n" );
document.write( "f(x) = 3[(x-3)^2 - 9]+11
\n" );
document.write( "f(x) = 3(x-3)^2 - 16   Vertex is Pt(3,-16), minimum at this Pt ( a>)
\n" );
document.write( " Line of symmetry is x = 3
\n" );
