    Well that will depend upon what "[[x]]" means! If it is the "floor" function, you should be able to calculate a few values at, say 0.5, 0.7, 0.9, 1.2, 1.4, 1.7, 2.5. 2.7, 2.9 and see for your self.

    Do you see that [[x]] is same as [x]? Plotting f(x) should be trivial once you notice that.

    (assuming [x] denotes the floor function)
