Transcript text: Graph the set $\{x \mid x \leq 5\}$ on the number line.
Then, write the set using interval notation.
\[
\{x \mid x \leq 5\}=
\]
$\square$
Solution
Solution Steps
Step 1: Understand the Set
The given set is \(\{x \mid x \leq 5\}\). This means we are looking for all values of \(x\) that are less than or equal to 5.
Step 2: Graph the Set on the Number Line
To graph \(\{x \mid x \leq 5\}\) on the number line:
Draw a number line.
Shade the region to the left of 5, including 5 itself (since \(x\) can be equal to 5).
Step 3: Write the Set Using Interval Notation
The interval notation for the set \(\{x \mid x \leq 5\}\) is \((-\infty, 5]\). This notation indicates that \(x\) can be any value from negative infinity up to and including 5.
Final Answer
The set \(\{x \mid x \leq 5\}\) in interval notation is \((-\infty, 5]\).
