\tt \:  \longrightarrow \: f(x) =  log(x)

☆ Differentiate w. r. t. x, we get

\tt \:  \longrightarrow \: f'(x) \:  =  \: \dfrac{1}{x}

☆ For maxima or minima

\tt \:  \longrightarrow \: f'(x) = 0

\tt \:  \longrightarrow \: \dfrac{1}{x}  = 0

\tt \:  \longrightarrow \: which \: is \: not \: possible

\tt \:  \longrightarrow \: Hence \: f(x) \: has \: no \: maximum \: and \: minimum \: value.
