5. its not c Which relation is a function?

{(–2, –12), (–2, 0), (–2, 4), (–2, 11)}

{(0, 1), (0, 2), (1, 2), (1, 3)}

{(–4, –6), (–3, –2), (1, –2), (1, 0)}

{(8, 1), (4, 1), (0, 1), (–15, 1)}

The answer is D. {(8, 1), (4, 1), (0, 1), (-15, 1)}

Step-by-step explanation:

It's not A because Since  

x

=

−

2

produces  

y

=

4

and  

y

=

11

, the relation  

(

−

2

,

−

12

)

,

(

−

2

,

0

)

,

(

−

2

,

4

)

,

(

−

2

,

11

)

is not a function.

The relation is not a function.

it's not B. because Since  

x

=

1

produces  

y

=

2

and  

y

=

3

, the relation  

(

0

,

1

)

,

(

0

,

2

)

,

(

1

,

2

)

,

(

1

,

3

)

is not a function.

The relation is not a function.

It's not C. because Since  

x

=

1

produces  

y

=

−

2

and  

y

=

0

, the relation  

(

−

4

,

−

6

)

,

(

−

3

,

−

2

)

,

(

1

,

−

2

)

,

(

1

,

0

)

is not a function.

The relation is not a function.
