Extreme value

"Minimum" and "Maximum" redirect here. For minimum or maximum of a function, see maxima and minima.

The largest and the smallest element of a set are called extreme values.

For a differentiable function f, if f(x₀) is an extreme value for the set of all values f(x), and if f(x₀) is in the interior of the domain of f, then x₀ is a critical point.
