Find all values x = a where the function is discontinuous. For each value of x, give the limit of the function as x approaches a. Be sure to note when the limit does exist. f(x) = 2x4+5x +4 Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice (Use a comma to separate answers as needed.) O A. f is discontinuous at the single value x = The limit is O B. f is discontinuous at the single value x = The limit does not exist and is not co or - co. O C. f is discontinuous at the two values x = The limit for the smaller value is The limit for the larger value is O D. f is discontinuous at the two values x = The limit for both values do not exist and are not co or - co. O E. f is discontinuous at the two values x = The limit for the smaller value does not exist and is not co or - co. The limit for the larger value is O F. f is discontinuous over the interval The limit is (Type your answer in interval notation.) O G. f is discontinuous over the interval The limit does not exist and is not co or - co (Type your answer in interval notation.) O H. f is continuous for all values of x. O I. f is discontinuous at the two values x = The limit for the smaller value is The limit for the larger value does not exist and is not co or - co
