The possibility graph of its derivative f' is

See the step by step solution

Step by Step Solution

Step 1. Given 

The given information is

Step 2. Explanation

From the above graph the function is decreasing on (- ∞, 0) : where f' <0 and increasing at (0, ∞) where f' >0 . Therefore, the possible graph of the derivative of above graph is shown below.

The graph of f' have roots at x = 0 and x = 2 . The graph off should "bounce" off the x

axis at x = 2
