Write the following intervals in set-builder form :
(i) `(-3,0)`
(ii) `[6,12]`
(iii) `(6,12]`
(iv) `[-23,5)`.

Explanation

To convert the given intervals into set-builder form, we will analyze each interval one by one.

### Step-by-step Solution:

**(i) Interval: `(-3, 0)`**

1. The interval `(-3, 0)` is an open interval, which means it does not include the endpoints.
2. We express this in set-builder notation as:
...
