1. **State the problem:** Find the value of the limit $$\lim_{x \to 4} (2x - 3)$$. 2. **Formula and rule:** For limits of polynomial or linear functions, the limit as $x$ approaches a value is simply the function evaluated at that value. 3. **Evaluate the function at $x=4$:** $$2(4) - 3 = 8 - 3 = 5$$ 4. **Conclusion:** The value of the limit is 5. Therefore, the correct answer is **b. 5**.
