    Given:

    The domain of function that is translated down 3 is (0, 4), (-5, 8), (4, -2).

    To find:

    The range of the function.

    Solution:

    If a function is translated 3 units down, then

    (x,y)\to (x,y-3)

    Using this rule, we get

    (0,4)\to (0,4-3)

    (0,4)\to (0,1)

    Similarly,

    (-5,8)\to (-5,5)

    (4,-2)\to (4,-5)

    The range of the given function is (0, 1), (-5, 5), (4, -5).

    Therefore, the correct option is A.
