Inequality problem

  1. Nov 1, 2013 #1
    1. The problem statement, all variables and given/known data
    Let f(x)=1-x-x3. Find all the real values of x satisfying the inequality, 1-f(x)-f3(x)>f(1-5x).


    2. Relevant equations



    3. The attempt at a solution
    I honestly don't know how to start with this one. Substituting f(x) directly in the inequality doesn't look like a good idea. I need a few hints to begin with.

    Any help is appreciated. Thanks!

    Problem solved. Sorry for the trouble, I should have thought upon it some more.
