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:
Many to one function.
Step-by-step 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.
[tex]y = x^2[/tex] 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.
