    The answer is E. Should I pick numbers for a and b?

    Don't you realise that when you multiply by fractions < 1, the result is smaller than what you started with?

    Re: Solving an equation

    No, you cannot just "pick numbers" because finding that, say, if x= 2 and y= 3, f(x)= (1/3)^2= 1/9> (1/3)^3= 1/27 is not sufficient to say that this is true for all numbers.
