The phrase "a function of levels" is correct and usable in written English.
It can be used in contexts where you are discussing how something varies or depends on different levels or degrees of a particular variable.
Example: "The effectiveness of the training program is a function of levels of participant engagement."
Alternatives: "dependent on levels" or "related to levels".
