WebJun 4, 2024 · Answer: f(3) = 326. Step-by-step explanation: Given the function. f(n)=f(n-1)^2+2. If f(1) = 4. f(2) = f(1)^2 + 2. f(2) = 4^2 + 2. f(2) = 16 + 2. f(2) = 18. f(3) = f ... 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]].
WebIf f(1)=1,f(n+1)=2f(n)+1,n≥1, then f(n) is: A 2 n+1 B 2 n C 2 n−1 D 2 n−1−1 Medium Solution Verified by Toppr Correct option is C) Given that f(n+1)=2f(n)+1,n≥1 . Therefore, f(2)=2f(1)+1 Since f(1)=1, we have f(2)=2f(1)+1=2(1)+1=3=2 2−1. Similarly f(3)=2f(2)+1=2(3)+1=7=2 3−1 and so on.... In general, f(n)=2 n−1 Webf 0 = d 1(x)f 1(x) −f 2(x),deg(f 2)
