Đạo hàm hàm số \(y = {\log _{2018}}\left( {2018x + 1} \right)\) là:

\(\left( {0;1} \right)\)

\(R\)

\(R\backslash \left\{ 0 \right\}\)

\(\left( {0; + \infty } \right)\)

\(y = {\log _2}\left( {x - 1} \right)\)

\(y = {\log _2}\left( {{x^2} - 1} \right)\)

\(y = {\log _2}\left( {{x^2} + 1} \right)\)

\(y = {\log _2}\left( {\sqrt x } \right)\)

$y' = \dfrac{{\ln 2017}}{x}.$

$y' = \dfrac{{{{\log }_{2017}}e}}{x}.$

$y' = \dfrac{1}{{x.\log 2017}}.$

$y' = \dfrac{{2017}}{{x.\ln 2017}}.$

$y' = \dfrac{1}{{x\ln 2}}$.

$y' = \dfrac{1}{{x\ln 10}}$.

$y' = \dfrac{1}{{2x\ln 10}}$.

$y' = \dfrac{{\ln 10}}{x}$.

$y' = \dfrac{2}{{2x + 1}}.$

$y' = \dfrac{1}{{2x + 1}}.$

$y' = \dfrac{2}{{\left( {2x + 1} \right)\ln 2}}.$

$y' = \dfrac{1}{{\left( {2x + 1} \right)\ln 2}}.$

$y = {\log _{\frac{{\sqrt 2 }}{2}}}x$.

$y = {\log _{\frac{e}{3}}}x$.

$y = {\log _{\frac{e}{2}}}x$.

$y = {\log _{\frac{\pi }{4}}}x$.
