document.write( "Using the vertex form of a parabola,  where(h,k) is the vertex
\n" );
document.write( "f(x)=3[(x-1)^2 -1]-2   |completing the square to put into vertex form
\n" );
document.write( "f(x)=3(x-1)^2 -5  Vertex is Pt(1,-5)
\n" );
document.write( "a = 3 >0 parabola opens upward  Pt(1,-5) a minimum point
