Step 1: Observe the graph of the function f(x). Identify the regions where the slope of the graph is negative, as this indicates that the function is decreasing.
Step 2: Look for intervals where the graph moves downward as x increases. This happens when the derivative f'(x) is less than zero.
Step 3: From the graph, note that the function decreases from x = -∞ to x = -2 and again from x = -2 to x = 1. These intervals correspond to the downward slopes of the graph.
Step 4: Write the intervals of decrease based on the observed behavior of the graph. The intervals are (-∞, -2) and (-2, 1).
Step 5: Verify the intervals by ensuring that the graph does not increase within these ranges. Confirm that the function transitions from decreasing to increasing at x = -2 and x = 1.
