Answer 1

Answer:

• The domain of $f$ is : {student}

• The range of $f$ is : {High Test Score, Low Test Score}

• $f$ is a function because  each student corresponds to one element of the range.

Step-by-step explanation:

Here are important things for a relationship to be a function:

• Every element in X is related to some element in Y.
• A function cannot have one-to-many relationship.
• A function must contain single valued

In the giving diagram of the question, it is clear that:

• Each student corresponds to one element of the range: High Test Score or Low Test Score.

Therefore,  $f$ is a function.

As domain of a function is the set of all the x-values of a ordered pair.

So,

The domain of $f$ is : {student}

And range of a function is the set of all the y-values of a ordered pair.

So,

The range of $f$ is : {High Test Score, Low Test Score}

Therefore, from the above discussion we conclude that  $f$ is a function because each student, or each element of the domain of the function corresponds to one element of the range.

Answer 2

Answer:

Step-by-step explanation:

The domain of f is  the students in Mrs. Conner's science class .

The range of f is  the test scores

f  is not  a function because each student, or each element of the  domain , corresponds to  more than one  element of the  range .
