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]]. WebLet R be a ring and X a non-empty set. Considering A = RX, describe the ring (A,+,⋅) 1) The zero divisors of RX are those functions which either vanishes somewhere or admits a zero divisor as value. 2) D is not stable under addition. Take for example f (x) = {1 if x ∈ A 0 otherwise and g(x) = {1 if x ∈ Aˉ 0 otherwise, ...
