The phrase "are used to extrapolate" is correct and usable in written English.
It can be used when discussing methods or processes that involve drawing conclusions or making predictions based on existing data or information.
Example: "In scientific research, various statistical models are used to extrapolate future trends from current data."
Alternatives: "are employed to infer" or "are utilized to derive".
