(x+16)(x-13)(x+8)>0
\n" ); document.write( "make the inequality sign an equal sign.
\n" ); document.write( "x=-16, x=13, x=-8
\n" ); document.write( "Test above, below and between the above numbers.
\n" ); document.write( "when x=-20 then y=-1584
\n" ); document.write( "when x=-10 then y=276
\n" ); document.write( "when x=-7 then y=-180
\n" ); document.write( "when x=14 then y=660
\n" ); document.write( ".
\n" ); document.write( "X(-16, -8) U (13, Infinity) This means that f(x)>0 when x is between -16 and -8 and also when x>13
