In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the local or relative extrema), or on the entire domain (the global or absolute extrema).

## Global minima

The smallest over the entire domain.

## Global maxima

The largest over the entire domain.

## Local minima

The smallest over a subset of the domain.

## Local maxima

The largest over a subset of the domain.
