Question
## Problem 7

Given the graph:

### (a)
Given \( P(x) = f(x)g(x) \), find \( P'(2) \).

### (b)
Given \( Q(x) = \frac{f(x)}{g(x)} \), find \( Q'(2) \).

### (c)
Given \( C(x) = f(g(x)) \), find \( C'(2) \).

### Graph Explanation

The graph displays two piecewise linear functions \( f \) and \( g \) plotted on a coordinate grid. The x-axis ranges from 0 to 3, and the y-axis ranges from 0 to 3, with each unit marked by grid lines.

- **Function \( g \)**:
  - Starts from point (0, 1).
  - Increases linearly to (1, 1).
  - Stays constant from x = 1 to x = 2.
  - Increases linearly from (2, 1) to (3, 2).

- **Function \( f \)**:
  - Starts from point (0, 0).
  - Decreases linearly to (1, -1).
  - Increases linearly from (1, -1) to (2, 1).
  - Increases linearly again from (2, 1) to (3, 3).
