Ex 6.5, 4 Prove that the following functions do not have maxima or minima: (ii) g(x) = log xGiven g (x) = log x Finding maxima or minima g‘ (x) = 1/𝑥 Putting g’ (x) = 0 1/𝑥=0 𝑥 =1/0 𝑥 = ∞ This is not defined for x. So, g (x) does not have a maxima or minima.

Next: Ex 6.5, 4 (iii) → Ask a doubt (live)
