State whether the following functions are odd or even.
`f(x) = (sin^(4)x)/([(x)/(2)]+(1)/(2)), x in (-2, 2)`

Explanation

To determine whether the function \( f(x) = \frac{\sin^4 x}{\frac{x}{2} + \frac{1}{2}} \) is odd or even, we will follow these steps:

### Step 1: Understand the Definitions
A function \( f(x) \) is:
- **Even** if \( f(-x) = f(x) \) for all \( x \) in the domain.
- **Odd** if \( f(-x) = -f(x) \) for all \( x \) in the domain.

### Step 2: Calculate \( f(-x) \)
