Someone please answer this question

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, 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 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 is : {Final Exam Score}

Hence, we conclude that is a function because each student, or each element of the domain of the function corresponds to one element of the range.  

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

i do not know this sorry : (
