Question

4 ≤ x < 8
4 < x ≤ 8
4 < x < 8
Match each domain to the equivalent interval notation domain.
[4, 8)
[4, 8]
(4, 8)
(4, 8]

Answer 1

Let's match each domain to its equivalent interval notation:

1. **4 ≤ x < 8**
- This means that x can be equal to 4 but is less than 8, so its interval notation is **[4, 8)**.

2. **4 < x ≤ 8**
- This means that x is greater than 4 but can equal 8, so its interval notation is **(4, 8]**.

3. **4 < x < 8**
- This means that x is strictly greater than 4 and less than 8, so its interval notation is **(4, 8)**.

So the matches are:

- **4 ≤ x < 8** → **[4, 8)**
- **4 < x ≤ 8** → **(4, 8]**
- **4 < x < 8** → **(4, 8)**
