We consider the function set to]0; + infinity[ g (x) = ln-x + 1 / x

A. Studying the variations of g

B. Show that the equation g (x) = 0, admits one and only one solution note (alfa) between 3/2 and 2

C. Consider the sign of g (x) sure everyone intervals]0;alfa[ and ]alfa; + infinity [

D. F is the function of R to R defined by f (x) = e ^ x-lnx

what the sign of f '
