    Answer:

    C. No; two range values exist for domain value –2.

    Step-by-step explanation:

    The relation is not a function.

    The -2 in the domain repeats

    Since  

    x

    =

    −

    2

    produces  

    y

    =

    0

    and  

    y

    =

    6

    , the relation  

    (

    −

    8

    ,

    −

    4

    )

    ,

    (

    −

    2

    ,

    0

    )

    ,

    (

    1

    ,

    3

    )

    ,

    (

    −

    2

    ,

    6

    )

    is not a function.

    The relation is not a function.
