The domain of the function graphed below is all real numbers, and all of its extreme values occur when -3 < x < 3. Use the graph to answer the following questions:
Identify all of the values of c for which h'(c) = 0. If there is more than one value, enter the values as a comma-separated list. If there are none, enter DNE.
Identify all of the values of c for which h'(c) does not exist. If there is more than one value, enter the values as a comma-separated list. If there are none, enter DNE.
