Refer to the graph to find each limit, if it exists: (a) $\lim _{x \rightarrow 2} f(x)$
(b) $\lim _{x \rightarrow 2} f(x)$
(c) $\lim _{x \rightarrow 2} f(x)$
|d) $\lim _{x \rightarrow 0} f(x)$
(e) $\lim _{x \rightarrow 0} f(x)$
(f) $\lim _{x \rightarrow 0} f(x)$

Key Concepts

Limit of a Function

A limit describes the behavior of a function as its input approaches a specific value. It focuses on the trend of the function's values rather than necessarily the value at that particular point, which is useful in determining overall behavior and handling undefined points.

One-Sided Limits

One-sided limits consider the behavior of a function as the input approaches a specific value from only one side—either from the left or the right. They are particularly useful for analyzing situations where the function may behave differently on either side of a point and play a key role in understanding discontinuities.

Existence of a Limit

A limit exists at a point if and only if the left-hand limit and the right-hand limit are both defined and equal to the same number. This concept is crucial in determining whether a function is approaching a unique value even if the function might not be continuous at that point.

Graphical Analysis of Limits

Graphical analysis involves studying a function's graph to infer its limit behavior as the input approaches specific values. It includes observing the approaching values of the function from either side and identifying any jumps, gaps, or asymptotic behaviors that inform the existence or value of the limit.

Discontinuities

Discontinuities occur when a function is not continuous at a particular point. Depending on whether the function fails to meet limit conditions, such as having matching left-hand and right-hand limits, discontinuities might be removable or jump discontinuities. Understanding these helps in accurately evaluating limits from a graph.
