document.write( "x = 0 is the equation of the vertical line (y-axis).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the parabola is symmetric relative y-axis.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means, that the the point symmetric to (9,4) relative y-axis also lies on the parabola.\r\n" );

document.write( "\r\n" );
document.write( "Answer.  The coordinates of another point of the parabola are  x= -9;  y= 4.\r\n" );
