6. its not b i need this answer QUICK!!

Which relation is a function?

{(5, 0,) (–8, –5)}

{(5, 0), (–8, –5), (–8, 5), (–5, –8)}

{(5, 0), (0, 5), (–5, –5)}

{(5, 0), (0, –8), (5, –5)}

The answer is A. {(5, 0), (-8, -5)}

Step-by-step explanation:

It's not B. because Since  

x

=

−

8

produces  

y

=

−

5

and  

y

=

5

, the relation  

(

5

,

0

)

,

(

−

8

,

−

5

)

,

(

−

8

,

5

)

,

(

−

5

,

−

8

)

is not a function.

The relation is not a function.

It's not C. because Since there is one value of  

y

for every value of  

x

in  

(

5

,

0

)

,

(

0

,

5

)

,

(

−

5

,

−

5

)

It's not D. because Since  

x

=

5

produces  

y

=

0

and  

y

=

−

5

, the relation  

(

5

,

0

)

,

(

0

,

−

8

)

,

(

5

,

−

5

)

is not a function.

The relation is not a function.
