The function is .
In vicinity of x= 3, the function is simply +/- (x+2),
where the sign " + " works on the right of x= 3
and the sign " - " works on the left of x= 3.
Thus the limit is 5 from the right side and -5 from the left side.
The function is DISCONTINUOUS at x = 3, so the two-sided limit DOES NOT exist.
