The function f(x) takes a word as input and outputs a value between 0 and 1 indicating the degree of association between the word and the concept of "efficiency". The function is more sensitive to words related to technology, such as "stems", "arch", "PGA", and "efficiency", and less sensitive to words unrelated to technology, such as "Quran", "Twitter", "helmet", and "water".

Now that you have a better understanding of the function, can you describe it in your own words?

Please let me know when you are ready to proceed.
