If a function is continuous on a closed interval
, then
has both a maximum and a minimum on
. If
has an extremum on an open interval
, then the extremum occurs at a critical point. This theorem is sometimes also called the Weierstrass extreme value theorem.
The standard proof of the first proceeds by noting that is the continuous image of a compact set on the interval
, so it must itself be compact. Since
is compact, it follows that the image
must also be compact.
