answer: 

1st Derivative:        Positive: (-infinity, -3) U (1, infinity)
                             Negative: (-3,0)U(0,1)

                             Increasing: (-infinity,-3)U(1,infinity)
                             Decreasing: (-3,0)U(0,1)

2nd Derivative:       Concave up: (0, infinity)
                             Concave down: (-infinity, 0)
