## anonymous one year ago Find the derivative of f(x) = negative 7 divided by x at x = -3

1. DecentNabeel

$\frac{d}{dx}\left(\frac{-7}{x}\right)=\frac{7}{x^2}$ then x replace -3 $\frac{7}{\left(-3\right)^2}=\frac{7}{9}$

Thanks

example Find the derivative of f(x) = negative 9 divided by x at x = -8. write it in index form f(x)=−9x−1 now find the derivative lastly substitute x = -8 into the derivative
