  (-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

It is increasing again from the local minimum on the right to the right side of the graph.

The two sections where the graph is increasing are ...

  (-∞, -5/2) ∪ (1, ∞)

__

The graph is <em>decreasing</em> between the maximum on the left and the minimum on the right.
