document.write( "y = -2x^2+4x+2    |Note use of ^ for squared term
\n" );
document.write( " y-intercept (when x = 0)  Pt(0,2)\r
\n" );
document.write( "\n" );
document.write( "y= -2(x-1)^2 + 4    |completing the square  Vertex Pt(1,4)
\n" );
document.write( " x-intercept (when y = 0)
\n" );
document.write( " -2(x-1)^2 + 4 =0
