the discontinuity is non-removable.
There's no way to define f(x) there so that the two limits are the same and equal f(x).
When one-sided limits are not equal to each other at a point, what can be said about the continuity of the function at that point?
I know that when one-sided are not equal to each other then the limit does not exist at that point. but i do not know what can be said about the continuity of the function at that point
