Question

a function in which the same y-value is never paired with two different x-values​

Answer 1

Answer:

One to One Function

Step-by-step explanation:

A function f is 1 -to- 1 if no two elements in the domain of f correspond to the same element in the range of f. In other words, each x in the domain has exactly one image in the range. ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1.

Answer 2

Answer:

A function in which the same y value is never paired with two different x values is called one-to-one function.

Step-by-step explanation:

One to one function:-

• A function that maps every element of the range to exactly one element of its domain.
• A one-to-one function is also known as injective function.

According to the question,

Since every element of the range is mapped to exactly one element of its domain.

Mathematically,

A function g(x) is said to be one-to-one if

g(x) = g(y) ⇒ x = y

for all elements x and y in its domain.

Therefore, a function in which the same y value is never paired with two different x values is called one-to-one function.
