Use the graph of F'(x) to answer questions about the function F(x). The domain of F(x) is (00, co) . This is the graph of F'(x). (a) Find the critical values for F(x) . (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) (b) Give the intervals where F(x) is increasing. (Enter your answer using interval notation. If an answer does not exist, enter DNE.) Ex (c) Give the intervals where F(x) is decreasing. (Enter your answer using interval notation. If an answer does not exist, enter DNE.) Ex (d) Find the x-coordinates of the relative extrema for F(x) . (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) Relative Maxima: |:| X Relative Minima: |:| X
