i need help with part c

Suppose f(x) is dened as shown below. 3. Use the continuity checklist to show that f is not continuous at 1. b. Is f continuous from the left or right at 1? 0. State the interval(s) of continuity. 2 . + Ifx>1 f(x): x 2x 2x ifxs1 a. Why is f not continuous at 1? 3A. Iim f(x) does not exist. x>1 B. Although Iim f(x) exists, it does not equal f(1). x>1 C. f(1) is not dened. b. Choose the correct answer below. A. f is continuous from the right at 'l. .V E. f is continuous from the left at 1. C. f is not continuous from the left or the right at 1. c. What are the interval(s) of continuity? D (Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed.)
