Question
### Problem Statement

If \( f \) and \( g \) are the functions whose graphs are shown, let \( u(x) = f(x)g(x) \) and \( v(x) = \frac{f(x)}{g(x)} \).

#### Graph Description

The graph is a coordinate plane with two lines representing the functions \( f(x) \) and \( g(x) \):
- The x-axis ranges from \(-2\) to \(6\).
- The y-axis ranges from \(-2\) to \(7\).

The blue line represents the function \( f(x) \):
- Starts below the x-axis at \( x = -2 \).
- Intersects the y-axis at \( y = 1 \).
- Continues to increase linearly, passing through \( (2, 2) \) and reaching \( (6, 4) \).

The red line represents the function \( g(x) \):
- Starts at \( (0, 2) \).
- Increases to \( (1, 4) \).
- Experiences a steep drop to \( (3, 0) \).
- Increases again linearly reaching \( (6, 6) \).

### Questions

(a) Find \( u'(1) \).

(b) Find \( v'(6) \).
