Step-by-step explanation: i got it right on the quiz.
The attached image represents the interval 2 < x ≤ 9 on the number line
<h3>How to highlight the interval?</h3>
The interval is given as:
2 < x ≤ 9
The above interval means that:
- 2 is exclusive of the values of x (because of the < inequality symbol)
- 9 is inclusive of the values of x (because of the ≤ inequality symbol)
In inequality, the < symbol uses an open circle, while the ≤ uses a closed circle
Next, we highlight the interval using the above rules (see attachment)
