Question

Find the points of inflection and the monotony of the function f(x)=exln(x)-e^x.Then solve the inequality f((2+f(x^2+x+1)/e))+e<0.

Answer 1

for inflection points, set 2nd derivative equal to 0
not sure what monotony of function is?

Answer 2

that inequality is crazy, it will make the function very complex and what does it have to do with inflection points?

Answer 3

It's done.If someone need to see the solution,let me know!Thanks.
