    f (9) = 1

    Step-by-step explanation:

    This questions asks us to find f (9).

    It is asking us to find what f (x), or y is, when x is equal to 9.

    f (x) = x-8

    Therefore, we can substitute 9 in for every x.

    f (9) = 9-8

    Subtract 8 from 9

    f (9) = 1

    If f (x) = x-8, then f (9) = 1
