Answer: Option B is correctExplanation:the Domain are the values that x will have a given function. In the case of the given function x can take all real numbers in the last instance to convert the integer greatest integer function.example [1.01] = 1range is the set of values of and. Here the values of y will be multiples of 3 and all will be whole numbers. Since then, all the real numbers, it will convert to integer by [x] . we have f(x) y = -3[x]and comes to be a whole-number multiple of 3. Therefore, The Option B.
