(i) Let y = -x(1/3)
Then y = -x(1/3) is the reflection of the graph of y = x(1/3) about the x-axis
(ii) Let y = x(1/3) + 1
Then y = x(1/3) + 1 is the x graph of y = x(1/3) shifts to the upward for one unit.
(iii) Let y = -x(1/3)
Then y = x(1/3) - 1 is the graph of x(1/3) shifts to the upward for unit.
(iv) y = (x + 1)(1/3)
>
y = (x + 1)(1/3) causes the graph of x(1/3) on the same co-ordinate plane.
