Functions of Arrays

Functions can be defined via

f[x1_, x2_] := x1^2 + x2^2

in Mathematica.


But how can I manage it to define a function depending on an array?
I would like to do something like

Array[x,2]
f[x[1]_,x[2]_]:=x[1]^2+x[2]^2

because the length of the array varies in my application.
