document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now the upper point has to be the vertex, and common sense \r\n" );
document.write( "tells you that the only way that the y-intercept can be way down\r\n" );
document.write( "there at -17, is for the parabola to open downward, like this:  \r\n" );
