The left-sided limit of a function at a point is the value that the function approaches as the input approaches that point from the left side. Similarly, the right-sided limit is the value that the function approaches as the input approaches the point from the right side. If the left-sided and right-sided limits are equal at a point, then the two-sided limit exists at that point. If the left-sided and right-sided limits are not equal, then the two-sided limit does not exist at that point. **
