1.Let a function f:N→Nf: \mathbb{N} \to \mathbb{N}f:N→N be defined by f(n)={2n,n=2,4,6,8,…n−1,n=3,7,11,15,…n+12,n=1,5,9,13,…f(n) = \begin{cases} 2n, & n = 2, 4, 6, 8, \ldots \\ n-1, & n = 3, 7, 11, 15, \ldots \\ \frac{n+1}{2}, & n = 1, 5, 9, 13, \ldots \end{cases}f(n)=⎩⎨⎧2n,n−1,2n+1,n=2,4,6,8,…n=3,7,11,15,…n=1,5,9,13,… Then fff is:Login to continueOnly logged in users canattempt or see the solution.
