Question

Please answer this question:

Answer 1

Step-by-step explanation:

A = {1, 2, 3, 4}

B = {1, 2, 3}

(I) A × B = { (1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3), (4,1), (4,2), (4,3) }

(II) Domain = {1, 2, 3, 4}

Range = {0, 1, 2, 3} but 0 does not belong to B

So, Range = { 1,2,3}
