📘 Topics Covered (Exercise 6.2 Part-1)

1️⃣ f(x) = 3x + 17 increasing on R
2️⃣ f(x) = e²x increasing on R
3️⃣ sin x का increasing/decreasing behaviour (0, π/2), (π/2, π)
4️⃣ f(x) = 2x² – 3x → Increasing/Decreasing Intervals
5️⃣ f(x) = 2x³ – 3x² – 36x + 7 → Nature of Function
6️⃣ Increasing/Decreasing Functions:

x² + 2x – 5

10 – 6x – 2x²

–2x³ – 9x² – 12x + 1

6 – 9x – x²

(x + 1)³ (x – 3)³

7️⃣ y = log(1 + x) – 2x/(2 + x) increasing function
8️⃣ y = [x(x – 2)]² increasing values of x
