.
Of function ?
Explain your question.
---------------------------------------
In connection with this problem, one can introduce and consider at least THREE
relevant functions:
- the current volume of the remaining water in the beaker (a linear function of time);
- the rate of evaporating water in the beaker (a constant function of time);
- the cumulated volume or mass of evaporated water (a linear function of time).
Therefore, in such problem, an accurate/professional Math writer will DEFINITELY write
WHICH function to consider: it is MANDATORY due to respect for the reader.
When the problem is worded as it is worded in this post, it clearly shows, that the author
is absolutely unprofessional and inaccurate writer, who is doing something that is not his business
and absolutely disrespects a reader (simply does not know what is it).
Accept and so on.
Do not forget to say " Thanks " to me for my teaching.

Amount of water is changing the same amount every day by a constant (until it is gone). Domain is time in days, and range is volume of water but you need to decide if you want as units of liters or as units of milliliters.
