The graph shows a function with critical points, regions of increase and decrease, and a clear inflection point. Let me address your two questions based on the graph:

1. Intervals of Decrease: The function is decreasing where the slope of the graph is negative. From observation:

   • The function decreases from around $x = -4$ to $x = -2$.
   • It also decreases from $x = 0$ to approximately $x = 1$.

   Therefore, the function is decreasing on the intervals: $(-4, -2) \cup (0, 1)$

2. **Inflection Point:
