Show that the sets are equivalent by carefully describing a one-to-one correspondence between the sets.The set of whole numbers and the set of even natural numbers:W = {0, 1, 2, 3, . . . } and E = {2, 4, 6, 8, . . . }.
What will be an ideal response?
The correspondence 0 ? 2, 1 ? 4, 2 ? 6, . . . , w ? 2w + 2, . . . shows that the sets are equivalent.
