question: can you please help me understand this equation

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. f(x)= x2 - 49 x - 7 (Use a comma to separate answers as needed.) O A. f is discontinuous at the single value x = . The limit does not exist and is not co or - co. O B. f is continuous for all values of x. O C. 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 D. f is discontinuous at the two values x = The limit for the smaller value is . The limit for the larger value is O E. f is discontinuous at the single value x = . The limit is OF. f is discontinuous at the two values x = The limit for both values do not exist and are not co or - co. 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 discontinuous over the interval . The limit is (Type your answer in interval notation.) Ol. 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
