Question

Let A = {4, 5, 6} and B = {6, 7, 8} and let S be the "divides" relation from A to B. That is, for every ordered pair

(x, y) A ✕ B,

x S y ⇔ x|y.

Using set-roster notation, state explicitly which ordered pairs are in S and

S⁻¹.

(Enter your answers as comma-separated lists of ordered pairs.)
