Show that the given set is an infinite set by placing it in a one-to-one correspondence with a proper subset of itself. (use n as your variable.) b (11, 15, 19, 23, 27, 31,, 4n+7,. ) let f (15, 19, 23, 27, then f is (4n +7) ( because b can be placed in a one-to-one correspondence with a proper subset of itself, b is an infinite set. 5. show that the given set has a cardinality of ko by establishing a one-to-one the elements of the given set and the elements c 1,1 4
