NCERT Class 12 Maths · Chapter 6 Applications Of Derivatives · Exercise 6.2 Question 2

Show f(x)=\(e^{2 x}\) is increasing on R.

💡 Concept Hints

  1. Identify the domain and the inner and outer functions, or the relevant one-sided limits.
  2. Apply the appropriate differentiation or limit rule, keep all chain factors, and check exceptional points.

✅ Step-by-Step Solution

Final Answer: Strictly increasing on R.
  1. Differentiate: f′(x)=\(2 e^{2 x}\).
  2. This derivative is positive for every real x, so the mean value theorem proves strict increase.
