Answer 1

See below.

Explanation:

That is a one-to-one function.

Answer 2

Answer: One-to-One function.

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
`If\ f(a) = f (b),\ then\ a = b` 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.
