Option fourth "The functions are not inverses because, for each ordered pair (x, y) for one function, there is no corresponding ordered pair (y, x) for the other function." is correct.
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have two tables shown in the picture.
Table (A) have values of x and a(x)
Table (B) have values of d and r(d)
As we know if the function has an inverse of it and (x, y) satisfies the function then (y, x) must satisfy the inverse of a function.
Thus, the option fourth "The functions are not inverses because, for each ordered pair (x, y) for one function, there is no corresponding ordered pair (y, x) for the other function." is correct.
