A lower bound in R is the smallest possible value that a set of numbers can have. It serves as a limit or boundary for the set, and all values in the set must be greater than or equal to the lower bound.
A lower bound can be proved in R by finding the smallest value in the set and showing that all other values are greater than or equal to it. This can be done through mathematical calculations or by using a visual representation, such as a number line.
An upper bound in R is the largest possible value that a set of numbers can have. It serves as a limit or boundary for the set, and all values in the set must be less than or equal to the upper bound.
An upper bound can be proved in R by finding the largest value in the set and showing that all other values are less than or equal to it. This can also be done through mathematical calculations or by using a visual representation.
Lower and upper bound proofs are important in R because they provide a way to determine the range and limits of a set of numbers. This information is crucial in many mathematical and scientific applications, such as optimization and data analysis. It also allows for a better understanding of the behavior and patterns within a given set of data.
