Examples 1 Let Z3 := {0,1,2} and define f : Z3 → Z3 via f (x)=2x + 1mod 3 Is f one-to-one? Is it onto? Is it bijective? 7 2 One-to-One and Onto Functions; Inverse
[PDF] Monday: Functions as relations, one to one and onto functions
A function f : A → B is one-to-one if for each b ∈ B there is at most one a ∈ A with f(a) = b It is onto if for each b ∈ B there is at least one a ∈ A with f(a) = b It is a one-to-one correspondence or bijection if it is both one-to-one and onto
[PDF] Chapter 10 Functions
Consider the function f : R → R, f(x)=4x − 1, which we have just studied in two examples We know it is both injective (see Example 98) and surjective (see

We illustrate with some examples Example 1 2 How many injective functions are there from a set with three elements to a set with four elements? How about a set
Functions, One-to-One, and Onto
Since f : Z → N is a well-defined function, f maps Z onto N Note that though the functions in the last two examples are quite different, the proofs that they are onto
