Use the graph y=f(x) to graph the given function
**Transcription for Educational Website**

**Task: Graphing a Function**

"Use the graph \( y = f(x) \) to graph the given function."

**Graph 1: \( y = f(x) \)**

- The graph is a blue triangle-shaped plot on a Cartesian plane.
- The x-axis and y-axis range from -8 to 8.
- The function forms a V-shape, with the vertex at the point (0, 8).
- The function intercepts the x-axis at (-8, 0) and (8, 0), indicating these are the roots.
  
**Graph 2: \( y = \frac{1}{9}f(x) \)**

- This graph is currently not plotted, represented as an empty coordinate plane.
- The axes range from -8 to 8 on both the x and y scales, just like the first graph.

**Explanation: Transformation of the Function**

The task involves transforming the original function \( y = f(x) \) by scaling it vertically. The function \( y = \frac{1}{9}f(x) \) represents a vertical compression by a factor of \(\frac{1}{9}\). This transformation will reduce the height of each point on the graph \( y = f(x) \) to \(\frac{1}{9}\) of its original value. Hence, the graph that currently peaks at 8 will peak at \(\frac{8}{9}\).

**Steps to Graph \( y = \frac{1}{9}f(x) \):**

1. Identify key points on the original graph, such as the vertex and x-intercepts.
2. Multiply the y-coordinate of each point by \(\frac{1}{9}\).
3. Plot the transformed points and connect them to maintain the V-shape.

This exercise demonstrates how transformations affect the shape and position of graphs in the coordinate system.
