Local Maximum/Minimum: A local maximum occurs when a function reaches its highest point within a specific interval, while a local minimum occurs when a function reaches its lowest point within that interval.

Critical Points:

These are points on a graph where either the derivative is zero or does not exist. They can be used to determine whether a function is increasing or decreasing.

Inflection Points:

These are points on a graph where the concavity changes. They can indicate transitions between increasing and decreasing behavior.
