first of all thanks for ure help. i didnt get any examples involving ln|x| inequalities anywhere. if u can tell me whre to see such examples, tht wud be nice anywys.. here's wht i did: b) so, if |x| = e^(2/3) then x = e^(2/3), -e^(2/3) these will be values which make F(x) = 0. right...

Homework Statement F(x) = (8-12ln|x|)/(x^4) > 0 (a) For what values of x is the expression F(x) defined? Write your answer in interval notation. (b) At what value(s) of x is the expression F(x) equal to zero? If there is more than one answer separate them by commas. (c) The set of...
