5. Continuity and Differentiation
medium

A value of $c$ for which the conclusion of mean value the theorem holds for the function $f(x) = log{_e}x$ on the interval $[1, 3]$ is

A

$log_e\ 3$

B

$log_3\ e$

C

$2\ log_3\ e$

D

$\frac{1}{2}{\log _e}\,3$

Solution

$f^{\prime}(x)=\frac{f(3)-f(1)}{3-1}$

$\frac{1}{x}=\frac{\ln 3-0}{2}$

$x=\frac{2}{\ln 3}=2 \log _{3} e$
