BOUNDED FUNCTION Meaning and
Definition
-
A bounded function is a term used in mathematics to describe a function that is restricted or limited in its range of values. A function is said to be bounded if there exists a specific value, referred to as a bound, which limits the range of the function. In other words, the values that the function can assume are restricted to a certain interval or range.
For example, consider a function f(x) defined on the real numbers. If there exists a number M such that for every input x, the absolute value of f(x) is less than or equal to M, then the function is said to be bounded. This means that the values of the function do not exceed the bound M in magnitude and are constrained within a certain range.
Bounded functions can have upper and lower bounds. An upper bound is the maximum value that the function can reach, while a lower bound is the minimum value. A function can be bounded from above, below, or both. If a function has a finite upper and lower bound, it is simply referred to as a bounded function.
In real-world applications, bounded functions are often encountered in areas such as economics, physics, and computer science. Understanding the concept of bounded functions is crucial in analyzing and solving various mathematical problems and equations.
