someone please answer this question

Answer:
[tex]f[/tex] is a function because each student, or each element of the domain of the function corresponds to one element of the range.
Step-by-step explanation:
Here are some of the important factors for a relationship to be a function.
As we know that a function is a relation between sets that associates to every element of a first set exactly one element of the second set.
In the giving diagram of the question, it is clearly observable that:
Therefore, [tex]f[/tex] is a function.
We know that the domain of a function is the set of all the x-values of an ordered pair of a set for which the function is defined.
Here,
The domain of [tex]f[/tex] is : {Student}
And range of a function is the set of all the y-values of a ordered pair of a set.
So,
The range of [tex]f[/tex] is : {Final Exam Score}
Hence, we conclude that [tex]f[/tex] is a function because each student, or each element of the domain of the function corresponds to one element of the range.
