Use the graph of the function f shown to the right to estimate the indicated function values and limits. Complete parts (A) through (E). (E) Is f continuous at x = -3? Explain. OA. The function is continuous. OB. The function is discontinuous at x = -3 since lim f(x)f(-3). X-3 OC. The function is discontinuous at x = -3 since f(-3) does not exist. OD. The function is discontinuous at x = -3 since lim f(x) does not exist. G
