Answer:
see attached
Explanation:
The changes in x and y are shown in the attachment. The changes in x are constant, but the changes in y appear to have no particular relation to each other:
- they are not constant, so the function is nonlinear
- they do not have a constant ratio, so the function is not exponential
- differences at increasing depth are not constant, so the function is not polynomial of degree less than 5
The product of x and y is not constant, so there is no inverse relationship.

Additional comment
6 points can always be matched by a polynomial function of degree 5 or less. The equation shown in the attachment comes from regression software that matches the given points exactly. No claim is made for any other values of x.
