Which of the following is/are true?

I. The derivative of

-x

-1.

II. The derivative of

(-{x})^{-1}

\frac{1}{{x}^2}

View answer and explanation

Correct option: A

Both I and II are true

Option A is correct because both statements are true. The derivative of -x is -1, and the derivative of (-x)^(-1) is 1/x².
