Section 7.2: One-to-One, Onto and Inverse Functions

WebThe function f is a one-to-one function and so a one-to-one correspondence exists between the set of KEY TERMS Function — A function is a set of ordered pairs (a,b) such that: a is a member of some set A and b is a member of some other set B, each pair of elements a and b are related to one another in the same fashion, and no two pairs have ... WebIf you want to show that a function, say f, is 1-to-1, then you typically consider two values x 1, x 2 in the domain of f such that f ( x 1) = f ( x 2). From this, if you can derive that x 1 = x 2, then your function is 1-to-1. Let's consider your first example. We would have f ( x 1) = 4 x 1 + 1 = 4 x 2 + 1 = f ( x 2). dash earbuds

Thus, T is one to one if it never takes two different vectors to the same vector. The second important characterization is called onto.
