Write the domain and range of the function `f(x)=[x]`

Explanation

To find the domain and range of the function \( f(x) = [x] \), where \( [x] \) denotes the greatest integer less than or equal to \( x \) (also known as the floor function), we can follow these steps:

### Step 1: Determine the Domain
The domain of a function is the set of all possible input values (x-values) for which the function is defined.

For the floor function \( f(x) = [x] \):
- The function is defined for all real numbers.
- Therefore, the domain is all real numbers.
