\n" ); document.write( "

Vertex form of a parabolic equation: , with (h, k) being the vertex' coordinates
\n" );
document.write( "With the line of symmetry being - 5, and the MINIMUM value being - 7, the vertex' coordinates = (h, k) = (- 5, - 7) 
\n" );
document.write( " then becomes: , and finally, the required equation: 
\n" );
document.write( "That's IT!! \n" );
