In Exercises, for all values of x = a where the function is discontinuous, determine if the discontinuity is removable or nonremovable.

Exercise 9

In Exercises, find all values x = a where the function is discontinuous. For each point of discontinuity, give 

(a) f (a) if it exists, 

(b)

(c)

(d) 

(e) Identify

which conditions for continuity are not met. Be sure to note when the limit doesn’t exist.
