Composition of Functions

If f(x) = 2x+1

find

A. f o f(x)

f(f(x)) = f(2x+1)

f(2x+1) = 2(2x+1)

f(f(x)) = 4x +2

B. f o f o f o f(x)

^ I dont get how to solve this one

C. f o f o f o f o f ...o f(x) n functions of f

^ I also dont get how to solve this one

given f(x) = ax+b and g(x) = cx+d and

f o g(x) = g o f(x), what is the relationship between a,b,c,d?
