The weightgap principle applies, where following rules are oriented strictly:
TRS Component: {g(x, y) -> x}
Interpretation of nonconstant growth:
-------------------------------------
The following argument positions are usable:
Uargs(g) = {}, Uargs(f) = {}, Uargs(s) = {1}
We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
Interpretation Functions:
g(x1, x2) = [1 0] x1 + [0 0] x2 + [2]
[0 1] [0 0] [0]
f(x1, x2, x3) = [0 1] x1 + [0 0] x2 + [0 1] x3 + [1]

[0]
1() = [0]
[0]
s(x1) = [1 0] x1 + [0]
[0 0] [0]
The strictly oriented rules are moved into the weak component.
