bounded function

A real function f (x) defined on a domain D for which there is a number M such that f(x) =M for all x in the domain D. It is an important result in mathematical analysis that if f(x) is a con- tinuous function on a closed interval be- tween a and b then it is also a bounded function on that interval.
