If the equation of the parabola is y=ax^2+bx+c
\n" ); document.write( "then the vertex is at [-b/2a , f(-b/2a)]
\n" ); document.write( "------------------
\n" ); document.write( "The vertex is the turning point of the parabola.
\n" ); document.write( "-------------------
\n" ); document.write( "If a>0 the vertex is the minimum point of the graph of the parabola.
\n" ); document.write( "If a<0 the vertex is the maximum point of the graph of the parabola.
