**Topic: Evaluating Limits Using a Table**

Consider the limit of \( f(x) \) as \( x \) approaches 4, where \( f(x) = \frac{x^2 - 16}{x - 4} \).

**A. Find the limit below if they exist by completing the following input-output table.**

**a.** \(\lim_{{x \to 4^-}} f(x)\)

| \(x \to 4^-\) | \(f(x)\) |
|---------------|----------|
| 3.9999        |          |
| 3.99          |          |
| 3.9           |          |

**b.** \(\lim_{{x \to 4^+}} f(x)\)

| \(x \to 4^+\) | \(f(x)\) |
|---------------|----------|
| 4.0001        |          |
| 4.001         |          |
| 4.01          |          |

**B. Find \(\lim_{{x \to 4}}\) of \(f(x)\) algebraically. Show all work.**
