Question
### Calculus: Finding the Second Derivative

In this exercise, we will explore how to find the second derivative of given functions. Follow the instructions provided to derive the solutions. Remember, *do not simplify* the final answers.

#### 4. Find \( y'' \)

a) \( y = (x^4 + x)^{\frac{3}{2}} \)

b) \( y = \frac{3}{x^4} - \frac{1}{x} \)

#### Find \( y(6) \):

c) \( y = x^4 - 3x^3 - 7x^2 - 6x + 9 \)

Explanation:

- Start by finding the first derivative \( y' \).
- Then, find the second derivative \( y'' \) without simplifying the final result.

For problem (c), evaluate the function \( y \) at \( x = 6 \) by simply substituting \( x \) with 6.

### Instructions:
1. Follow the chain rule and product rule where necessary.
2. Pay close attention to the functions and their components.
3. Execute differentiation accurately to find \( y'' \).
4. For the evaluation question, ensure proper substitution.

This set of problems will help you practice your differentiation skills and understand how to apply these techniques in various scenarios.
