5. A relation pairs elements in the domain with elements in the range. The table below defines a relation where the domain is represented by the x-values and the range is represented by the y-values.
Which of the following statements indicates whether this relation is a function of x and provides a valid reason?
F. It is, because the y-value is always greater than the x-value.
G. It is, because there are 5 distinct values in both the domain and the range.
H. It is not, because there are 2 different y-values paired with the x-value 3.
J. It is not, because there are 2 different x-values paired with the y-value 5.
K. It is not, because no equation can be written to model the relationship between x and y.
