Write of the domain and range of `f(x)=sqrt(x-[x])dot`

Explanation

To find the domain and range of the function \( f(x) = \sqrt{x - [x]} \), where \([x]\) denotes the greatest integer function (or floor function), we can follow these steps:

### Step 1: Understand the Function
The function can be rewritten as:
\[ f(x) = \sqrt{x - [x]} = \sqrt{\{x\}} \]
where \(\{x\} = x - [x]\) is the fractional part of \(x\).
