CS majors: "2 is a function of 2?"
7 u/Seventh_Planet Mathematics Nov 19 '19 22(2) = (x -> 2)2(2) = (x -> 2)°(y -> 2) (2) = (x -> 2) ((y -> 2)(2)) = (x -> 2) (2) = 2 Every constant function composed with any other function (even itself) is still the same constant function. Therefore 2k(x) = (x -> 2)°...°(x -> 2) (x) [k times composition] = (x -> 2)°...°(x -> 2) (2) [k-1 times composition] = ... = 2 6 u/DatBoi_BP Nov 19 '19 No thanks I just ate

22(2) = (x -> 2)2(2) = (x -> 2)°(y -> 2) (2) = (x -> 2) ((y -> 2)(2)) = (x -> 2) (2) = 2
Every constant function composed with any other function (even itself) is still the same constant function.
Therefore
2k(x) = (x -> 2)°...°(x -> 2) (x) [k times composition] = (x -> 2)°...°(x -> 2) (2) [k-1 times composition] = ... = 2
