Local Maximum: A local maximum refers to the highest point of a function within a specific interval. It is higher than all nearby points but may not be higher than all other points on the entire function.
Critical Points: Critical points are points on a graph where either the derivative is zero or does not exist. They can be used to find important information about functions such as relative extrema and inflection points.
