One-Sided Limit: A one-sided limit focuses on either approaching from the left side or approaching from the right side of a specific point to determine if there's an existing limit.
Continuity:Continuity refers to when there are no sudden jumps or breaks in a function's graph. In terms of limits, it means that both one-sided limits exist and are equal at every point within an interval.
Discontinuity:Discontinuity occurs when there is a sudden jump or break in a function's graph. It indicates that the function does not have a limit at that specific point.
