Function Relation Fun Facts!
Which of the following scenarios exhibits a function relation? Take the first set listed to be the domain of the relation.
A. the set of tree heights and the set of trees in a forest
B. the set of car make and models and the set of people in a certain town
C. the set of birthdays and the set of students in a class
D. the set of people with Social Security cards and the set of Social Security numbers
Answer:
The scenario that exhibits a function relation is option D: the set of people with Social Security cards and the set of Social Security numbers.
The mapping between two sets, the inputs and outputs that result in ordered pairs of the type is defined by a function relation. There is no obvious correlation between the number of trees in a forest and the height of a tree in the presented question.
The same is true for car makes and models in a certain town. There is categorically no connection among students in a class and birthdays as standalone pieces of data.
However, there is a direct correlation among the number of social security numbers and the number of SS Cards since a big number is required so that everyone who needs a social security number may have a unique numeric representation of their Social Security.
