On what intervals is the function decreasing? Name them in interval notation and highlight the intervals on the graph as well.
If you 'read' the graph from L to R....which sections are going downward?
thanks, so the intervals to answer the question are [-8,-4] [0,8] ?
To be nit-picky ...... we should have [-8, -4) U (0, 8]
[ At x -4, the function isn't increasing or decreasing.....same at x = 0 ]
