After teasing us with a short video displaying the girls' dance abilities but failing to unveil the members, [b]SM Entertainment[/b] has officially released photos of the five member girl group, [b]f(x)[/b]. Along with the pictures, it is now known that [b]f(x)[/b] will debut this September with their single [b]LACHATA[/b]. And the 'x' in 'f(x)' is like a variable, where if the 'x' changes, the result will be different. Which correlates to the members diverse skills and backgrounds, which will allow them to not only flourish in Korea, but by changing their x-factor or variable, they will also succeed overseas - as that is the plan. In addition, the 'f' stands for 'flower', and the 'x' stands for the female chromosome 'xx'. And like a flower, they will blossom and become hot icons to represent Asia as the top "Asian Pop Dance Group." Stay tuned to [b]allkpop[/b] as we continue to bring you the latest coverage on f(x)! And for those of you still wondering, f(x) is pronounced "effects." [b]Victoria[/b] [b]Krystal[/b] [b]Sulli[/b] [b]Amber[/b] [b]Luna[/b]
