    You have the number 8 listed twice in the range, so I'll ignore that.

    There are 4! = 24 possible functions with that domain and range.

    To narrow down that list, I'll assume that the numbers correspond in the order given, i.e. f(9) = -8, f(8) = -9, f(-9) = 5, f(5) = 8. In that case:

    f(x) = (269/360)x^3 - (3641/720)x^2 + (7327/720)x - (839/120)
