The graph of a continuous function is shown. a. List any critical numbers b. Classify each critical number. 4- 3- 2- 1- 8 9 10 a The critical numbers are x= (Type whole numbers. Use a comma to separate answers as needed. Use ascending order.) b. List any critical number(s) which correspond to horizontal tangents. OA. At x= the function has a horizontal tangent (Use a comma to separate answers as needed. Use ascending order.) OB. The function has no horizontal tangents. List the critical number(s) which correspond to vertical tangents OA. At x= the function has a vertical tangent (Use a comma to separate answers as needed Use ascending order) OB. The function has no vertical tangents List the critical number(s) which correspond to cusps
