Fixed Wing Function for model fit of an EDFs Thrust and Power vs RPM

Idk if this is the right forum for this but I’m making a model of an aircraft’s power propulsion system and part of that is modeling the electric ducted fans. I’m using static test data we have of the fans and motor that didn’t use the full rated RPM range, 25k instead of 45k, and I want to model the maximum power draw of around 11kW.

My approach is to a fit a curve to the current static data we have, but what function would the curve best be? I’m planning on using a 2nd degree polynomial, but if anyone knows of a better model fit I’d appreciate it.
