Transcribed Image Text:### Graph Analysis and Interpretation
The image contains a graph with a Cartesian coordinate plane. The \( x \)-axis is labeled, and the \( y \)-axis is labeled as \( f(x) \). A red line passes through several points on the graph, representing the function \( f(x) \).
#### Detailed Explanation:
- **Axes:**
- The \( x \)-axis and \( y \)-axis intersect at the origin (0,0).
- The \( x \)-axis is labeled with values ranging from -8 to 8.
- The \( y \)-axis has values ranging from -8 to 8.
- **Line:**
- The red line passes through multiple plotted points, showing a linear function.
- Key points visible on the graph include approximately (0, -4), (1, -2), (2, 0), (3, 2), and (4, 4).
#### Question:
- **What is the value for \( f(x) \) when \( x = -1 \)?**
#### Finding the Value:
1. Locate \( x = -1 \) on the \( x \)-axis.
2. Trace vertically to the point where it intersects with the red line.
3. The intersection occurs approximately at \( f(x) = -6 \).
Therefore, the value of \( f(x) \) when \( x = -1 \) is -6.
