Q10. Please answer all the parts to this question 

The graphs of the functions \( f \) and \( g \) are shown in the figure.

**Graph Description:**

- The blue graph represents the function \( f \).
- The green graph represents the function \( g \).
- The \( x \)-axis ranges from \(-1\) to 6.
- The \( y \)-axis ranges from 0 to 4.

**Function \( f \):**

- Starts at \( (-1, 0.5) \), rises to \( (1, 2) \), peaks at \( (3, 4) \), and then descends to \( (6, 2) \).

**Function \( g \):**

- Begins at \( (0, 4) \), decreasing linearly to \( (3, 1) \), and then increases to \( (6, 3) \).

**Mathematical Expressions:**

Let \( u(x) = f(x)g(x) \) and \( v(x) = \frac{f(x)}{g(x)} \).

**Tasks:**

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

(b) Find \( v'(5) \).
