Say \(f_{n}(x)=x^n\). Then \(f_{1}(n)=x\) \(f_{2}(x)=x^2\), etc. Shourya Pandey · 4 years, 3 months ago

Its just a name given to a polynomial. Vikram Waradpande · 4 years, 3 months ago

It's like any other subscript of any other variable. It just denotes that this is function n out of a family of functions specified by some criteria. Bob Krueger · 4 years, 3 months ago
