F n f n−1 +f n−2 if n 1 in python
Webf −1[f [A]] is a set, and x is an element. They cannot be equal. The correct way of proving this is: let x ∈ A, then f (x) ∈ {f (x) ∣ x ∈ A} = f [A] by the definition of image. Now ... Since you want to show that C ⊆ f −1[f [C]], yes, you should start with an arbitrary x ∈ C and try to show that x ∈ f −1[f [C]].

(b) The answer for (a) shows that F (n) is O (2^n). If we could also show that F (n) is Ω (2^n), that would mean that F (n) is Θ (2^n), and our order of growth would be F (n).
