Question

find intervals where f(x)= lnx/x is increasing and decreasing.

Answer 1

f'(x)= (1 - lnx)/x^2

Answer 2

x> 1 inicreasing
x<1 decreaseing
is this?

Answer 3

i need to know how to find the answer

Answer 4

f(x) = (ln (x))/x
df(x)/dx = (x(1/x) +1(lnx))/x^2

Answer 5

\[\prime(x)=(1+\ln x)/x^2\]

Answer 6

and then i m confused lol
