Sovi AI helps me figure out why i got it wrong instead of just memorizing the answer All Subjects Name: NU ID Number: 1. [32 Points] The following graph is of the DERIVATIVE f'(x). Using the graph, answer the following questions. y = f'(x) A B C D E F G (a) As what x-values do the critical points of the unknown function f(x) occur? (Select all that apply.) OA OB OC OD OE OF OG (b) Find all open intervals on which f(x) is increasing. Find all open intervals on which f(x) is decreasing. Write your final answer in the blocks provided. Increasing: Decreasing: (c) Determine the x-values of all local minima of f(x). (Select all that apply.) OA OB OC OD OE OF OG (f) Determine the x-values of all the inflection points of f(x). (Select all that apply.)
