document.write( "Hi,
\n" );
document.write( "y= -x^2/2+3x+8 
\n" );
document.write( "0 = -x^2/2+3x+8  | x-intercepts when y = 0
\n" );
document.write( "0 = x^2 - 6x -16 = (x-8)(x+2)  x-intercepts (8,0)(-2,0)
\n" );
document.write( "the vertex form of a parabola,  where(h,k) is the vertex
\n" );
document.write( "y= -x^2/2+3x+8     |complete the square of the original EQ
\n" );
document.write( "y= -(1/2)[ x-3)^2 -9] + 8 
\n" );
document.write( "y= -(1/2)[ x-3)^2 + 25/2  V(3,12.5)\r
