Draw the graph of `f(x) ={2x}`, where `{*}` represents the fractional part function.

Explanation

To draw the graph of the function \( f(x) = \{2x\} \), where \(\{*\}\) represents the fractional part function, we will follow these steps:

### Step 1: Understand the Fractional Part Function
The fractional part function \(\{x\}\) is defined as:
\[ \{x\} = x - \lfloor x \rfloor \]
where \(\lfloor x \rfloor\) is the greatest integer less than or equal to \(x\). This means that the fractional part of a number is the non-integer part of that number.
