Question

1.If A = { 1, 2 } and B = { 1, 2, 3} find the relation R: A →B in ordered pairs such that
x = y, x ∊ A and y ∊ B.
2. If P = { 0, 2, 4, 6 } and Q = { 1, 3, 4 } then show the relation from P to Q with y > x in the arrow diagram.
3. Find the relation R = {(x, y): x + y > 7 } if M = { -1, -2, -3 } and N = { 8, 9, 10 }. Also represent R in tabular form.

Answer 1

Answer:

1.If A = { 1, 2 } and B = { 1, 2, 3} find the relation R: A →B in ordered pairs such that

x = y, x ∊ A and y ∊ B.

2. If P = { 0, 2, 4, 6 } and Q = { 1, 3, 4 } then show the relation from P to Q with y > x in the arrow diagram.

3. Find the relation R = {(x, y): x + y > 7 } if M = { -1, -2, -3 } and N = { 8, 9, 10 }. Also represent R in tabular form.
