i need help please and thank you !

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 doesn't exist. K(X) = 4 e VX -B Select the correct choice below and, if necessary, fill in the answer box(es) within 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 the smaller value is . The limit for the larger value does not exist and is 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 L. f is discontinuous at the two values x = The limits for both values do not exist and are not co or - co
