4. The function at) is given in the graph below. No explanations are required for this problem. (a) (b) (4 points) Circle all of the following x-values where f(;t':) has a critical point. (4 points) In parts (b) and (c), let 9(3) be a function such that 9"(3?) = an). Circle all of the following zit-values where g(:r) has a. critical point. (4 points) Classify each of the mvaluee you circled in part (b) as the location of a local min, a local max or neither for 9(32). (d) (4 points) Let h(:r) be a function such that h\"(m) = x). Circle all of the following m-values where Mar] has an inection point
