I was flipping on my phone. Searching information about f(x).

f(x) (Hangul: 에프엑스) is a South Korea-based girl group formed by S.M. Entertainment 2009. Since their debut, f(x) has released four full-length albums, two extended plays, and one repackaged album. The group is currently composed of four members: Victoria, Amber, Luna, and Krystal.
