SOLUTION: What is the solution of function g^2,g^3,g^4,g^5,g^6 and g^30? The question give : g(x)=(x-1)/(x+1). I had ask my teacher,he said g^4(x)=x g^8(x)=x g^12(x)=x g^16(x)

Question 619163: What is the solution of function g^2,g^3,g^4,g^5,g^6 and g^30?
The question give :
g(x)=(x-1)/(x+1).
I had ask my teacher,he said
g^4(x)=x
g^8(x)=x
g^12(x)=x
g^16(x)=x
g^20(x)=x
g^28(x)=x
g^2g^28(x)=?
g^2(x)=-(1)/(x)
and can you prove to me why my teacher say like above?
Thank You..
