Answer: One-to-One function.
Step-by-step explanation:
A One-to-One function (also written as 1-1) is that function for which every element of the Range corresponds to one and only one element of the Domain.
Given a Set A (Domain of a function) and a Set B (Range of the function), if [tex]If\ f(a) = f (b),\ then\ a = b[/tex] and it is a One-to-One function.
Given the graph of a function, you can determine if it is a One-to-One function if it passes the Horizontal Line Test.
The conclusion is: A function in which each y-value has only one corresponding x-value is called a One-to-One function.
