The rule that would represent this function is:

3%5Ex=y where x is all integer values from 0 to 4.

This is because:

3%5E0=1

3%5E1=3

3%5E2=9

3%5E3=27

3%5E4=81

There is no real way to learn these relations. It just takes practice learning to see numerical patterns.

In this case I was sure the pattern had something to do with 3 because of the nice y values including 3, 9, 27, etc.

I hope this helps! :)
