Answer:

the domain is:

{

3

,

0

,

1

,

6

}

the range is:

{

2

,

3

,

4

,

6

,

4

}

the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Explanation:

In the relation:

{

(

3

,

2

)

,

(

0

,

3

)

,

(

1

,

4

)

,

(

1

,

6

)

,

(

6

,

4

)

}

:

The domain:

Is the set of all the first numbers of the ordered pairs.

In other words, the domain is all of the x-values.

So in this case the domain is:

{

3

,

0

,

1

,

6

}

The range:

Is the set of the second numbers in each pair, or the y-values.

So in this case the range is:

{

2

,

3

,

4

,

6

,

4

}

A relation is a function if it has only One y-value for each x-value.

So in this case the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Answer:

the domain is: { − 3 , 0 , 1 , 6 }

the range is: { 2 , 3 , 4 , − 6, 4 }

the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Step-by-step explanation:

In the relation: { ( − 3, 2) , ( 0 , 3 ) , ( 1 , 4 ) , ( 1 , −6 ) , ( 6 , 4 ) } :

The domain:

Is the set of all the first numbers of the ordered pairs.

In other words, the domain is all of the x-values.

So in this case the domain is: {− 3 , 0 , 1 , 6 }

The range:

Is the set of the second numbers in each pair, or the y-values.

So in this case the range is: { 2 , 3 , 4 , − 6, 4 }

A relation is a function if it has only One y-value for each x-value.

So in this case the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Have a good day/night!
