What does it mean when a function is not bounded?
unbounded
In mathematics, a function f defined on some set X with real or complex values is called bounded if the set of its values is bounded. In other words, there exists a real number M such that. for all x in X. A function that is not bounded is said to be unbounded.

And ifMoreAll you basically want to do is just say you know does the graph go go below a certain value. And if it doesn’t then it’s bounded below if the graph doesn’t go above a certain value above.
How do you show a function is not bounded variation?
+ ( 1 m + 1 + 1 m ) = 1 m + 2 Since the harmonic series diverges, the above sum increases to ∞ as n→∞ n → ∞ . Accordingly, the total variation must be infinite, and the function f is not of bounded variation on [0,a] ….References.

Can a function be continuous but not bounded?
A function is bounded if the range of the function is a bounded set of R. A continuous function is not necessarily bounded. For example, f(x)=1/x with A = (0,∞).
Which function is not continuous?
In other words, a function is continuous if its graph has no holes or breaks in it. For many functions it’s easy to determine where it won’t be continuous. Functions won’t be continuous where we have things like division by zero or logarithms of zero.
How do you know if its bounded or unbounded?
Bounded and Unbounded Intervals An interval is said to be bounded if both of its endpoints are real numbers. Bounded intervals are also commonly known as finite intervals. Conversely, if neither endpoint is a real number, the interval is said to be unbounded.
How do you write a bounded function?
A function f(x) is bounded if there are numbers m and M such that m≤f(x)≤M for all x . In other words, there are horizontal lines the graph of y=f(x) never gets above or below.
Are bounded functions of bounded variation?
In mathematical analysis, a function of bounded variation, also known as BV function, is a real-valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense.
