Question

Find the derivative of f(x) = negative 7 divided by x at x = -3

Answer 1

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

Answer 2

Thanks

Answer 3

no problem @Nairz

Answer 4

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

Answer 5

example Find the derivative of f(x) = negative 9 divided by x at x = -8.
write it in index form

f(x)=−9x−1
