Increasing, Decreasing, and Concavity

The f(x) = x^3 - 6x^2 + 12x + 6 has the following intervals: (-oo,5)U(7,oo)

Can someone tell me what interval is this function decreasing, what interval is the concave downward and upward, and what is the limit as x approaches positive and negative infinity??

please help, i've been struggling with this question a lot!
