Termination w.r.t. Q of the following Term Rewriting System could be proven:

Q restricted rewrite system:
The TRS R consists of the following rules:

f(x, a) → x
f(x, g(y)) → f(g(x), y)

Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:

f(x, a) → x
f(x, g(y)) → f(g(x), y)

Q is empty.

We use [23] with the following order to prove termination.

Recursive path order with status [2].
Precedence:
f2 > g1

Status:
f2: [2,1]
