Consider the graph of y= f(z) shown below in blue. Find the open interval(s) where f'(z) is negative. Select the number of intervals in your answer by sliding the red point on the upper left corner of the graph. Then move the black points to the appropriate x-coordinates to define the intervals. Notice that the movable points are labeled as the "Left" or "Right" endpoint of each interval. If an interval's endpoint is too or -co, then move the corresponding endpoint to the very edge of the graph. Provide your answer below: Number of Intervals -10 Left Right 10 -10 5 0 Left 14 Right 10
