Answer:
The function is increasing on the intervals (-∞, -1) and (2, ∞)
The function is decreasing on the intervals (-1, 2)
The domain of the function is (-∞, ∞)
Explanation:
In order to see where the function is decreasing or increasing, check the x values to see where it is the rise and where it is fall. The domain of the function is never-ending so it is (-∞, ∞)
