### Understanding Limits with Rational Functions

Consider the following function:
\[ f(x) = \frac{x^2}{x^2 - 16} \]

### Completing the Table
We want to explore the behavior of \( f(x) \) as \( x \) approaches \(-4\). Complete the following table by calculating \( f(x) \) for each given value of \( x \). Round your answers to two decimal places.

| \( x \)    | \(-4.5\) | \(-4.1\) | \(-4.01\) | \(-4.001\) | \(-4\) | \(-3.999\) | \(-3.99\) | \(-3.9\) | \(-3.5\) |
|------------|----------|----------|-----------|------------|-------|------------|-----------|----------|----------|
| \( f(x) \) |          |          |           |            |   ?   |            |           |          |          |

### Evaluating Limits
Use the table to determine whether \( f(x) \) approaches \( \infty \) or \( -\infty \) as \( x \) approaches \(-4\) from the left and from the right.

\[ \lim_{{x \to -4^-}} f(x) = \]
\[ \lim_{{x \to -4^+}} f(x) = \]

### Instructions:
1. **Calculate \( f(x) \)**: For each \( x \) value in the table, compute the function \( f(x) \) and fill in the corresponding cell.
2. **Analyze the Limits**: Use the table values to infer the behavior of \( f(x) \) as \( x \) approaches \(-4\) from the left side (\( x \to -4^- \)) and from the right side (\( x \to -4^+ \)).
3. **Fill in Limit Values**: Based on the function's behavior near \( x = -4 \), determine if the function approaches positive infinity (\( \infty \)), negative infinity (\( -\infty \)), or if it is undefined.

By understanding how to find the limit of a rational function through numerical substitution and pattern recognition, you can apply these methods to a variety of functions and improve your understanding of limits and continuity in mathematical
