Draw the graph of f(x)=x+[x], [.] denotes greatest integer function.

Explanation

To draw the graph of the function \( f(x) = x + [x] \), where \([x]\) denotes the greatest integer function (also known as the floor function), we can follow these steps:

### Step 1: Understand the Greatest Integer Function
The greatest integer function \([x]\) gives the largest integer less than or equal to \(x\). For example:
- If \(0 \leq x < 1\), then \([x] = 0\).
- If \(1 \leq x < 2\), then \([x] = 1\).
- If \(2 \leq x < 3\), then \([x] = 2\).
- If \(-1 < x < 0\), then \([x] = -1\).
