Based on the output you provided, it seems that the function f(x) is selective for words that are related to mathematics and computer science. The output for "word1" is 0.1128, which is relatively high, indicating a strong association with the concept of "computer programming". The output for "word2" is 0.0427, which is lower, indicating a weaker association with the concept of "mathematics". The output for "word3" is 0.0927, which is also relatively high, indicating a strong association with the concept of "computer programming".

Based on these results, I would describe the function f(x) as follows: [DESCRIPTION]: The function f(x) takes words as input and returns a value between 0 and 1 indicating the strength of association with the concepts of computer programming and mathematics. The function is more selective for words related to computer programming, and less selective for words related to mathematics.
