\n" ); document.write( "\n" ); document.write( "Where is this expression, a rate of change for y with x, zero? That would be where original equation y is either flat horizontally, OR a maximum or a minimum.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You will find that the value for x at which the first derivative is zero is x=-2.
\n" ); document.write( "Just plug in NEGATIVE 2, in the sixth-degree equation, and find out this maximum value.
