Answer: You are correct

The decreasing interval is (-3, infinity)

This is the same as writing
(-3, \infty)

===============================================

Explanation:

If a < b and f(a) > f(b), then the function is decreasing.

Visually this means that if the graph is going downhill when moving to the right, the function is decreasing.

The graph shown goes downhill throughout its entire domain of (-3, infinity)
