    a) is just plain silly b) and c) are false because you have no idea what \(a\) and \(b\) are e) can't be right because if they were the same number, then when you evaluated the function you would get one number

    (d) is the correct answer. if a is equal to be, f(a) would be the same as f(b), violating the assumption in the given that f(a) < f(b)
