The solution to an inequality is represented by the number line.

How can this same solution be written using set-builder notation?

[tex]\(\{x \mid x\ \textgreater \ 1\}\)[/tex]



Answer :

Sure, let's break down how you can express the solution to the inequality [tex]\(x > 1\)[/tex] using set-builder notation in a detailed, step-by-step manner.

1. Identify the Inequality:
The given inequality is [tex]\(x > 1\)[/tex], which tells us that we are looking for all values of [tex]\(x\)[/tex] that are greater than 1.

2. Understand Set-Builder Notation:
Set-builder notation is a way of specifying a set by stating the properties that its members must satisfy. It is usually written in the format:
[tex]\[ \{ \text{variable} \mid \text{condition} \} \][/tex]
where the vertical bar [tex]\( \mid \)[/tex] can be read as "such that," and the condition is a characteristic that defines the elements of the set.

3. Construct the Set-Builder Notation:
For the inequality [tex]\(x > 1\)[/tex], we want to denote the set of all [tex]\(x\)[/tex] such that [tex]\(x\)[/tex] is greater than 1. In set-builder notation, this is written as:
[tex]\[ \{ x \mid x > 1 \} \][/tex]

4. Interpret the Notation:
The set-builder notation [tex]\(\{ x \mid x > 1 \}\)[/tex] reads as "the set of all [tex]\(x\)[/tex] such that [tex]\(x\)[/tex] is greater than 1." This succinctly captures the solution to the inequality.

Combining all these steps, the solution to the given inequality [tex]\(x > 1\)[/tex] in set-builder notation is:

[tex]\[ \{ x \mid x > 1 \} \][/tex]
