The function f(x) seems to be selective for multiple concepts. It appears to assign higher values (closer to 1) to words that are associated with the concept of "boats" and "championships". Words such as "boats" and "championships" have high associations with the concept, as indicated by their output values of 0.9511 and 0.2783 respectively. On the other hand, words like "money", "faith", and "serif" have extremely low values, suggesting little or no association with the concept.
