Provide an appropriate response.Give an example of a function f(x) that is continuous for all values of x except 
where it has a nonremovable discontinuity. Explain how you know that f is discontinuous at 
and why the discontinuity is nonremovable.
What will be an ideal response?
Let f(x) = 
, for all x ? 4. The function f is continuous for all 
and 
As f is unbounded as x approaches 4, f is discontinuous at 
, and, moreover, this discontinuity is nonremovable.
