comment To find the general formula of $\overbrace{g(g(g(…g(x))}^\text{n}=g_n(x)=\frac{A_{n}.x+B_{n}}{C_{n}.x+D_{n}}$
I understood that how to get matrix result. I had applied in my question. I will try to get result via eigenvalues . Thanks

comment To find the general formula of $\overbrace{g(g(g(…g(x))}^\text{n}=g_n(x)=\frac{A_{n}.x+B_{n}}{C_{n}.x+D_{n}}$
how can that relation be proved? Please advice a method.

It is very nice. I wonder something if it is possible to express $A_n,B_n,C_n,D_n $ as exponential functions as we can do for $F_n$ or not?

Really nice approach: I liked the way you used $Z(x)=e^x$ in $U$ Function . It made very easy proof and also thanks for generalized formula.

@marco trevi: It is the function that depends on x
