    The 1st table represents a function

    Step-by-step explanation:

    * Lets explain how to solve the problem

    - Function is a relation where each input has a single output

    - The notation of the function is f (x) = y, where x is the input of the

    function and y is the out put of the function

    - The domain of the function is x and the range of the function is y

    * Lets find which table represent a function

    # First table:

    x y

    -3 - 1

    0 0

    -2 - 1

    - In the first table

    ∵ - 3 has only - 1

    ∵ 0 has only 0

    ∵ - 2 has only - 1

    ∵ 8 has only 1

    ∵ Every x has a single y

    ∴ The table represents a function

    ∴ The 1st table represents a function

    - In the second table

    x y

    -5 - 5

    0 0

    -5 5

    6 - 6

    ∵ x = - 5 has y = - 5 and y = 5

    ∴ One x has two values of y

    ∴ The table doesn't represent a function

    - In the third table

    x y

    -4 8

    -2 2

    -2 4

    0 2

    ∵ x = - 2 has y = 2 and y = 4

    ∴ One x has two values of y

    ∴ The table doesn't represent a function

    - In the fourth table

    x y

    -4 2

    3 5

    -4 0

    ∵ x = - 4 has y = 2 and y = 0

    ∴ One x has two values of y

    ∴ The table doesn't represent a function
