Jan 14, 2019 at 22:31 comment added Ismael Ghalimi And I am still wondering about the minus sign on the numerator. If x is greater or equal to 1, don’t you want f(x) to be positive always? I have updated the answer accordingly. Please let me know if I got it wrong. It’s kinda late where I am right now...
