To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to. ( f + g ) ( x) = f ( x) + g ( x) = [3 x + 2] + [4 − 5 x] = 3 x + 2 + 4 − 5 x = 3 x − 5 x + 2 + 4

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]]. WebSteps to simplifying fractions.
