Question

Find the derivative of f(x) = negative 5 divided by x at x = 11.

Answer 1

-5/x = -5x^(-1) right?

Answer 2

then use power rule a*x^(n) -> a*n*x^(n-1)

Answer 3

im lost

Answer 4

that's ok,
do you at least understand how
-5/x = -5x^(-1) ? :)

Answer 5

yes i get that

Answer 6

then have you learn the power rule?
that given x^n
then derivative of that would be n x^(n-1)

Answer 7

is the answer

121 divided by 5

Answer 8

close but not quite ^_^
just flip it

Answer 19

sorry @adamj8034 I'm not as good at trig as I am at calc
you're perhaps better off making a new question post for your question :/

Answer 20

its fine. thanks!
