**Question 9:** Graph at least four steps for the function \( y = \left\lfloor x \right\rfloor \), also called \( y = \text{int}(x) \).

**Explanation:**

The function \( y = \left\lfloor x \right\rfloor \), known as the floor function or greatest integer function, outputs the greatest integer less than or equal to \( x \). The graph of this function is a step function, characterized by horizontal line segments that are open on the left and closed on the right at each integer \( x \).

To construct the graph:
- For each integer \( n \), plot a horizontal line segment from \( (n, n) \) to \( (n+1, n) \), with an open circle at \( (n+1, n) \).
- Repeat this process for at least four steps to capture the basic shape and nature of the floor function.
