### Description of the Graph and Problem

The graph depicts a function \( f \) with points plotted on a coordinate grid. The x-axis ranges from 0 to 5, and the y-axis ranges from -5 to 7. The function shows different linear segments forming a piecewise function:

1. From \( x = 0 \) to \( x = 2 \), the function is a rising line starting at \( (0, -4) \) and going to \( (2, 1) \).
2. From \( x = 2 \) to \( x = 4 \), the function rises more steeply from \( (2, 1) \) to \( (4, 6) \).
3. From \( x = 4 \) to \( x = 5 \), the function is a declining line from \( (4, 6) \) to \( (5, 0) \).

### Mathematical Problem

The question pertains to this graph:

10. The graph of a function \( f \) is shown above. If \( g \) is the function defined by
\[ 
g(x) = \frac{x^2 + 1}{f(x)}, 
\]
what is the value of \( g'(2) \)?

#### Options:
(A) \(-\frac{8}{9}\)

(B) \(\frac{1}{9}\)

(C) 1

(D) \(\frac{32}{9}\)

### Explanation of Derivatives and Function Analysis

To find \( g'(2) \), you need to first determine \( f(2) \) and the derivative \( f'(2) \) using the segments of the function. Use this information with the quotient rule or relevant calculus techniques to differentiate \( g(x) \) and find the desired value at \( x = 2 \). Consider the critical points, slopes, and behavior of the piecewise segments.
