A function in which each y-value has more than one corresponding x-value is called a:

Answer 1

A function in which each y-value has more than one corresponding x-value is called a one-to-one function.

To add, one to one function is a function for which every element of the range of the function corresponds to exactly one element of the domain.

Answer 2

Many to one function.

Explanation:

Given:

A function in which each y-value has more than one corresponding x -value.

Which means two domains have one range.

Here x values are called domain and y values are called range or codomain.

If there are each y value that have more than one x value mapped, then it is called many to one function.

For example.

`y = x^2` is many to one function.

When x = -1 and x = 1, the y value is 1

When x = -2 and x = 2, the y value is 4.

You can see each y-value has more than one corresponding x-value.
