Question

If P = {positive integers} and subset T = {positive integers divisible by 3}, what is T′?

){1, 2, 3, 4, …}

{ nothing}

{3, 6, 9, 12, …}

{1, 2, 4, 5, 7, 8, 10, 11, 13, 14, …}




Let A = {circle, square} and let B = {3, 4, 5}. Find A X B.

){circle, square, 3, 4, 5}

{nothing }

{3, 4, 5}

{(circle, 3), (circle, 4), (circle, 5), (square, 3),

(square, 4), (square, 5)}



The domain of the following relation: R: {(−6, 3), (2, 6), (−3, 1), (3, 6)} is

{6}.

{1, 3, 6}.

No domain exists.
