adding polynomic functions in Comsol 3.5A

I'm new in the Comsol world and, I want to add a 5th degree polynomic function in a cuasi-statics, electric model, and I dont know how.
My function is frequency dependent, its range is between 1e-3 and 1e7 Hz, and needs to be added on a subdomain of the model.
This is the polynom: a0+a1*log10(freq)+a2*(log10(freq))^2+a3* (log10(freq))^3+a4* (log10(freq))^4+a5* (log10(freq))^5
What steps should I make for succeeding?
Should I define the polynomic coefficients as "Constants" or as "Subdomain Variables"?
Thank you!
