Use set notation, and list all the elements of each set. {x | x is a natural number greater than 8 and less than 15}

Key Concepts

Set Notation

Set notation is a mathematical way to describe a collection of objects, known as elements. It often uses curly braces to enclose the elements or a rule to define the elements that belong to the set. For example, the notation {x | condition} indicates a set of all x that satisfy the given condition.

Natural Numbers

Natural numbers are the set of positive integers starting from 1 and extending indefinitely (1, 2, 3, ...). In this context, natural numbers are used to define the elements of the set, specifically those that are greater than 8 and less than 15. Understanding the range of natural numbers is crucial for identifying the specific elements of the set.

Inequalities

Inequalities are mathematical expressions that describe the relative size or order of two values. In this case, the inequalities 'greater than 8' and 'less than 15' define the boundaries for the natural numbers included in the set. Solving inequalities helps in determining which elements meet the specified conditions.
