Their debut studio album, Pinocchio (2011), and their two extended plays Nu Abo and Electric Shock produced three number-one singles on South Korea's Gaon Digital Chart. Their acclaimed second studio album, Pink Tape (2013), was the only K-pop album on US music channel Fuse's "41 Best Albums of 2013",[1] the only idol album to be featured in Korean critics' definitive list of "Top 100 Classic Albums of All Time",[2] and was named "Greatest K-pop Album of the 2010s" by Billboard.[3] The group's third and fourth albums, Red Light (2014) and 4 Walls (2015), were commercially successful and well received by music critics. Following the release of the SM Station single "All Mine" in 2016, the group halted group promotions and the members have embarked on individual music, acting, and modelling careers. In August 2019, f(x) officially reunited as a three-piece (without Victoria) and performed at the three-night SM Town Live 2019 in Tokyo concert.
Known for their eclectic, electropop-based sound, f(x) is one of the first few recognized K-pop groups internationally, becoming the first K-pop act to perform at SXSW. In 2017, Billboard ranked f(x) at number seven on their "Top 10 K-pop Girl Groups of the Past Decade" list.[4]
Name
f(x) is used as the notation for functions in mathematics. It is used to symbolize their various activities, based on the various talents and attractiveness of the members, like a function in which the output or results change depending on the input value of x. In addition, "f" symbolizes flower and "x" symbolizes 'X' on the female chromosome XX which, taken together, symbolizes "flower reminiscent of women".[5]

2019–2021: Reunion and departures from SM
In an interview with Krystal on January 19, 2018, she stated that the members frequently discussed making a comeback but timing never worked out.[44] [45] [46]
In August 2019, f(x) officially reunited and performed together at the three-night SM Town Live 2019 in Tokyo concert as a three-piece (without Victoria).[47] On September 1, Amber announced via her social media accounts that she had not renewed her contract with SM Entertainment.[48] On September 5, SM Entertainment shared that Luna had also not renewed her contract with the company; Victoria also announced her departure from SM on her Instagram, but SM instead reported that Victoria's contract with them was still under discussion.[49] Victoria was eventually reported to remain in SM in some capacity.[50] On October 12, 2020, it was announced that Krystal had officially left SM, and had signed an exclusive contract with H& Entertainment.[51]
On April 9, 2021, SM announced Victoria's contract with them had expired.[52] On April 23, during a review video of her activities from debut to present, Luna expressed confusion over f(x) being referred to in the past tense, stating that the group had not yet disbanded.[53] [54]
Impact
In an industry focused more on mini-albums, f(x)'s discography leaned more towards full-length studio albums, releasing four internationally acclaimed albums during their time as a group. In 2015, while reviewing 4 Walls, American music magazine Spin called f(x) the "world's greatest living pop group" at the time.[55] In 2017, Billboard ranked f(x) at number seven on their "Top 10 K-pop Girl Groups of the Past Decade" list.
"Rum Pum Pum Pum" and "4 Walls" were both included on Billboards "The 100 Greatest K-pop Songs of the 2010s" staff list, at numbers 33 and 9, respectively. Billboard also noted that "Ice Cream Cake" represents a baton pass from f(x) to Red Velvet as the best idol group alive, meaning that f(x) was the former holder of the title.[56]
