\( \log x - x \)
\( x \log x \)
1
\( e^{\log x} \log x \)
Show Solution
Verified By Collegedunia
The Correct Option is
C
Solution and Explanation
Step 1: Differentiating the function.
The derivative of \( y = \log x \) with respect to \( x \) is: \[ \frac{dy}{dx} = \frac{1}{x} \]
Step 2: Conclusion.
Thus, the derivative of \( y = \log x \) is 1, corresponding to option (C).
