Question

Which of the following scenarios exhibits a function relation? Take the first set listed to be the domain of the relation.

-the set of tree heights and the set of trees in a forest
-the set of car make and models and the set of people in a certain town
-the set of birthdays and the set of students in a class
-the set of people with Social Security cards and the set of Social Security numbers

Answer 1

-the set of people with Social Security cards and the set of Social Security numbers

Step-by-step explanation:

There's literally no relation between the height of a tree and the number of trees in a forest that can be clearly seen. Same goes to models and people in a certain town. Birthdays and Students in Class definitely have no correlation as isolated pieces of information. The number of people with social security numbers and the amount of numbers in a SS Card, though, have a direct relation, since the number has to be large so the amount of people that need such a number can have unique numeric representations of their Social Security.

Answer 2

For the answer to this question, the right answer is the last one among the choices, the set of people with Social Security cards and the set of Social Security numbers.

I hope my answer helped you. Have a nice day!`
