document.write( "It depends on what you're given.  The parts of a parabola are:\r\n" );
document.write( "\r\n" );
document.write( "vertex (h,k), p = directed distance for the vertex to the focus, which\r\n" );
document.write( "is also the directed distance from the directrix line to the vertex.\r\n" );
document.write( "\r\n" );
document.write( "If it opens upward or downward the standard equation is\r\n" );
document.write( "\r\n" );
document.write( "{x - h)² = 4p(y - k), upward if p is positive, downward if p is negative.\r\n" );
document.write( "\r\n" );
document.write( "If it opens rightward or leftward the standard equation is\r\n" );
document.write( "\r\n" );
document.write( "{y - k)² = 4p(x - k), rightward if p is positive, leftward if p is negative.\r\n" );
