The table shows the relationship between r and s, where s is the independent variable.

s 1 2 3 4 5 6
r 16 13 12 23 56 1

Which equation represents the relationship between r and s?

1. Well, it's not linear or exponential or sinusoidal, so the next thing to try is polynomial. Not easy, the way it rises and falls so unevenly. It will have to be at least degree 5, so good luck with that. I get

r(s) = -s^5 + 15s^4 - 250/3 s^3 + 216s^2 - 785/3 s + 131
