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...
