Q2. In a scenario where a car's speed is given by \(v(t) = 3t + 2\) (mph) for \(0 \leq t \leq 4\) hours, which rectangle method (left, right, or midpoint) would give the exact distance?

🔹 A. Left‑endpoint

🔹 B. Right‑endpoint

🔹 C. Midpoint

🔹 D. All of the above

💡 Difficulty: medium | ✅ Correct: C

Q3. Why does the rectangle method fail to give an exact area for functions with discontinuities within the interval?
