Draw the graph of the step funcation f (x) = [ x ].

Explanation

To draw the graph of the step function \( f(x) = [x] \), where \([x]\) denotes the greatest integer less than or equal to \(x\), we will follow these steps:

### Step 1: Understand the Definition
The greatest integer function \([x]\) gives the largest integer that is 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 \(3 \leq x < 4\), then \([x] = 3\)
