suppose f(x)= 1/x then (f∘ f∘ f)(x)=

Answer 1

If it helps, you can define a function g(x) = (f °f)(x), then find the result of (f°g)(x).

You can simply find g(x) = 1 / (1/x), which is simply x.

Then find (f°g)(x) = 1 / (x) = 1/x

Therefore, (f°f°f)(x) = 1/x is simply 1/x.

Answer 2

1/(1/(1/x))

(f (f ( f(x))) = 1/ x
