If the sign in front of the \"x%5E2\" term is positive, then the parabola looks like a cup sitting on a table.
\n" ); document.write( "If the sign of the \"x%5E2\" term is negative, then it's an upside down cup
\n" ); document.write( "Try a simple example, \"y+=+-x%5E2\"
\n" ); document.write( "This is the upside-down cup with peak at (0,0) becase all other possible y's are negative
\n" ); document.write( "
\n" );
