Answer 1

Answer:

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

Explanation:

$\displaystyle\frac{d}{d x } \left( \frac{ 1 }{ x } +4 \right)$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$-x^{-1-1}$

$-x^{-2}$

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