Ex 6.2, 10 Prove that the logarithmic function is strictly increasing on (0, â).f(đĽ) = log (đĽ) We need to prove f(đĽ) in increasing on đĽ â (0 , â) i.e. we need to show fâ(đ) > 0 for x â (đ , â) Now, f(đĽ) = log đĽ fâ(đĽ) = 1/đĽ When đ > 0 (1 )/đĽ > 0 fâ(đĽ) > 0 â´ f(đĽ) is an increasing function for đĽ > 0 Hence, f(đĽ) is an increasing function for (0, â). Hence proved
