The phrase "as a function of the density" is correct and usable in written English.
It is typically used in scientific or mathematical contexts to describe how one variable changes in relation to the density of a substance or material.
Example: "The pressure of the gas increases as a function of the density, indicating a direct relationship between the two variables."
Alternatives: "in relation to the density" or "depending on the density".
