Show that the function f:N→N, given by f(1)=f(2)=1 and f(x)=x−1 for every x>2, is onto but not one-one.Easy
Question
Solution 1
Sure, let's break this down:
-
A function f: N→N is said to be onto (or surjective) if for every element y in the co-domain N, there is at least one element x in the domain N such that f(x) = y.
For the given function f(x), we can see that for any y in N, we can always find an x in N such tha Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
