One-sided limit

A one-sided limit refers to the value that a function approaches as the input approaches a particular point from one side, either the left or the right. There are two types of one-sided limits: 1. **Left-Hand Limit**: This is denoted as \( \lim_{x \to c^-} f(x) \) and represents the value that \( f(x) \) approaches as \( x \) approaches \( c \) from the left (i.e.
