Extrema on an Interval

The minimum and maximum of a function on an interval are the extreme values, or extrema (the singular form of extrema is extremum), of the function on the interval.  The minimum and maximum of a function on an interval are also called the absolute minimum and absolute maximum on the interval.

  • A function does not need to have a maximum or minimum
  • Extrema that occur at endpoints of an interval are called endpoint extrema
