\n" ); document.write( "

This is a parabola with a HORIZONTAL AXIS of SYMMETRY, and so, its equation is: 
\n" );
document.write( "Given equation: 
\n" );
document.write( "After COMPLETING the SQUARE on y, we get: 
\n" );
document.write( "Comparing that to the equation of a parabola with a HORIZONTAL AXIS of SYMMETRY, or , we see that:
