You can put this solution on YOUR website!
Use simple qualitative knowledge about shape of polynomial functions. Increases toward the left toward negative infinity and increases toward the right toward positive infinity because degree is EVEN.\r

\n" ); document.write( "\n" ); document.write( "Zeros at -3, -1, 2, 5.\r
\n" ); document.write( "\n" ); document.write( "Decreasing at -3; increasing at -1; decreasing at 2; increasing at 5.\r
