Transcribed Image Text:### Understanding The Function \( f(x) \)
The plot below represents the function \( f(x) \).
**Graph Description:**
- The graph consists of a single line plotted in a coordinate plane.
- The x-axis (horizontal) ranges from -5 to 5.
- The y-axis (vertical) ranges from -2 to 8.
- The line intersects the y-axis between the points 2 and 3.
- The slope of the line is positive, indicating that the function is increasing.
**Question:**
Solve for \( f(x) = 2 \).
**Options:**
- \( A. \ -3 \)
- \( B. \ 3 \)
- \( C. \ 2.6 \)
### Explanation:
To solve \( f(x) = 2 \) using the graph:
1. Locate the y-value of 2 on the y-axis.
2. Find the corresponding x-value where the line intersects this y-value.
**Answer:**
The correct x-value where \( f(x) = 2 \) is approximately \( -1 \). Therefore, the answer is:
- \( A. \ -3 \) is incorrect.
- \( B. \ 3 \) is incorrect.
- \( C. \ 2.6 \) is incorrect.
So, none of the given options is correct based on the graph. The actual x-value is around -1.
