Step-by-Step Solution

Answer

The  possibility graph of its derivative f' is  

Step 1. Given

The given information is  

Step 2. Calculation

From the above graph, f'>0 at (- ∞, - 1) and (2, ∞) ; the function is increasing from (- ∞, - 1) and (2, ∞) ; the graph f' <0 at (-1,2) where the function is decreasing.
