The second and fourth selections represent a translation to the right by 1 unit. The fourth selection represents a vertical reflection about the x-axis. The picture shown can be considered to be a right translation and a vertical reflection of
![\sqrt[3]{x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20)
.
