Answer:

Analyzed ans Sketched.

Explanation:

We are given the function:


y = 8 \ln (x)/x^2

The first derivative of y:


y' = (8x-16x\ln(x))/(x^4) =(8-16\ln(x))/(x^3) =0

The root
x = \sqrt e is absolute maximum.

The second derivative of y:


y''=(-16x^2-24x^2+48x^2\ln(x))/(x^6) =(48\ln(x)-40)/(x^4) =0

The root
x = e^(5/6) is point where concavity changes from down to up.

x = 0 is vertical asymptote.

y = 0 is horizontal asymptote.

The sketch is given in the attachment.
