Draw the graph of `f(x) = "sgn"(log _(e) x)`.

Explanation

To draw the graph of the function \( f(x) = \text{sgn}(\log_e x) \), we will follow these steps:

### Step 1: Understand the Signum Function
The signum function, denoted as \( \text{sgn}(x) \), is defined as follows:
- \( \text{sgn}(x) = -1 \) if \( x < 0 \)
- \( \text{sgn}(x) = 0 \) if \( x = 0 \)
- \( \text{sgn}(x) = 1 \) if \( x > 0 \)
