Let A = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4} and define a relation R on A as follows: For all x, y E A, x R y ↔ 3|(x - y). It is a fact that R is an equivalence relation on A. Use set-roster notation to write the equivalence classes of R. [0] [1] = [2] = [3] = = How many distinct equivalence classes does R have? classes List the distinct equivalence classes of R. (Enter your answer as a comma-separated list of sets.)
