help please
The graph of f' on the interval [- 8, - 3] is shown in the figure. On what interval(s) is f increasing? Decreasing? Find the critical points of f. Which critical points correspond to local maxima? Local minima? Neither? At what points does f have an inflection point? On what intervals is f concave up? Concave down? On what interval(s) is f increasing? Decreasing? Select the correct choice below and, if necessary, fill in the answer box(es) within your choice. The function is increasing on and decreasing on . (Type your answers in interval notation. Use a comma to separate answers as needed.) The function is increasing on .The function is never decreasing. (Type your answer in interval notation. Use a comma to separate answers as needed.) The function is decreasing on .The function is never increasing. (Type your answer in interval notation. Use a comma to separate answers as needed.) The function is never increasing nor decreasing.Explanation / Answer
f(x) is
increasing on -7 to -3
decreasing on -8 to -7
Critical points are -7 and -5
Inflection points are -6 and -5
Concave up in the regions [-8 ,-6] and [-5,-3]
Concave down in the region [-6,-5]
