Textbook Question

Determine whether each statement is true or false. 6 ∈ {2, 5, 8, 9}

Verified step by step guidance

Understand the symbol \( \in \), which means 'is an element of'.

Identify the set given in the problem: \( \{2, 5, 8, 9\} \).

Check if the number 6 is listed as one of the elements in the set.

Since 6 is not listed among the elements \( \{2, 5, 8, 9\} \), determine the truth value of the statement.

Conclude whether the statement '6 \( \in \) \{2, 5, 8, 9\}' is true or false based on your findings.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Set Notation

Set notation is a mathematical way to describe a collection of distinct objects, known as elements. In this context, the notation {2, 5, 8, 9} represents a set containing the numbers 2, 5, 8, and 9. Understanding set notation is crucial for determining whether a specific element belongs to a set.

Element Membership

Element membership refers to the relationship between an element and a set, denoted by the symbol '∈'. If an element is part of a set, we say it is a member of that set. For example, in the statement 6 ∈ {2, 5, 8, 9}, we are checking if 6 is a member of the specified set.

True or False Statements

True or false statements are assertions that can be evaluated as either true or false based on logical reasoning or definitions. In this case, determining the truth value of the statement 6 ∈ {2, 5, 8, 9} involves checking if the number 6 is included in the set, which is essential for answering the question accurately.
