8 questions tracing function execution. Q1: def f(x): return x*2; print(f(f(3))) → 12 (f(3)=6, f(6)=12). Q2: def g(a,b): return a+b; x=g(2,3); y=g(x,x); print(y) → 10. Q3: def h(lst): lst.append(4); return lst; a=[1,2,3]; b=h(a); print(a) → [1,2,3,4] (lists are mutable!). Q4: def mystery(n): if n<=1
