Question
**Title: Graphing Reflected Functions**

**Objective:** Learn how to graph functions after applying reflections.

**Function:** The given function is \( k(x) = (-x)^3 \).

**Task:** Graph the function by applying an appropriate reflection.

**Graph Description:**

The graph is represented on a coordinate plane with both x and y axes ranging from -8 to 8. The plotted function, \( k(x) = (-x)^3 \), appears as a blue curve.

**Function Analysis:**

1. **Symmetry and Reflection:**
   - The function \( k(x) = (-x)^3 \) can be considered a reflection of \( x^3 \) across the y-axis.
   - This reflects all points such that if a point (x, y) is on the original \( x^3 \) graph, then the point (-x, y) is on the reflected graph.

2. **Shape of the Graph:**
   - The graph shows typical cubic behavior: it passes through the origin (0,0).
   - As x approaches 8, y increases rapidly, and as x approaches -8, y decreases.

3. **Transformations:**
   - Since the graph is \( (-x)^3 \), this is reflected over the y-axis compared to the graph of \( x^3 \).

**Interactive Features:**

- **Transform Tools:**
  - The interface includes options for manipulating the graph:
    - An arrow cross indicates the capability to move the graph.
    - A trapezoid shape suggests a zoom feature to expand or contract the view.
    - A reset symbol is available for undoing changes and resetting the graph.

**Conclusion:** Understanding reflections allows for better mastery of function transformations and their graphical representations. Use the interactive features to practice applying reflections and observe their effects on various functions.
