The domain of the piecewise function is (- 00,00). a. Graph the function. b. Use your graph to determine the function's range. 4 if xs -1 f(x) = -4 if x> -1 a. Choose the correct graph below. O A. OB. Oc. OD. b. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The range does not have any isolated values. It can be described by (Type your answer in interval notation.) O B. The range has at least one isolated value. It can be described as the union of the interval(s) and the set {}. (Use a comma separate answers as needed.) O C. The range consists exclusively of one or more isolated values. It can be described as { }. (Use a comma to separate answers as needed.)
