Here in practice test on math relation will help the students to get more ideas about the questions on math relation. The questions are mainly related to ordered pairs, Cartesian products of two sets, representation of math relation and also domain and range of a relation. Depending on these topics there are various questions related to practice test on math relation worksheet.

Find R domain and range of R.
9. Let A = {3, 4, 5} and B = {6, 8, 9, 10, 12}. Let R be the relation 'is a factor of' from A to B. Find R.
10. Adjoining figure shows relation between A and B. Write relation in
(i) Set builder form.
(ii) Roster form.
(iii) Find domain and range of R.
Answers for practice test on math relation will help the students to check the exact answers of the given questions.
1. Domain = {1, 3, 5, 7} Range = {p, r, q}
2. R₃
3. R ={(3, 4) (3, 5) (3, 6) (4, 5) (4, 6) (5, 6)}

4. R = {(1, 1) (2, 1) (3, 1) (4, 1) (5, 1) (6, 1) (7, 1) (8, 1) (9, 1) (10, 1) (4, 2) (6, 2) (8, 2) (10, 2) (6, 3) (9, 3) (8, 4) (10, 5)}
Domain = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Range = {1, 2, 3, 4, 5}
5. Domain = {1, 2, 3, 4} Range = {4, 5, 6, 7}
6. Domain = {1, 2, 3, 4} Range = {3, 4, 5, 6}
7. R = {(x, y) : y = 3x, x ∈ A, y ∈ B } R = {(1, 3) (2, 6) (3, 9) (4, 12) (5, 15)}
Domain = {1, 2, 3, 4, 5} Range = {3, 6, 9, 12, 15}
8. Domain = {1, 4, 9} Range = {1, 2, 3}
R = {(1, 1) (4, 2) (9, 3)}
9. R = {(3, 6) (3, 9) (4, 8) (5, 10)}
10. R = {(x, y) : x = y², x ∈ A,y ∈ B} = {(1, 1) (1, 1) (4, 2) (4, 2) (9, 3) (9, 3) (16, 4) (16, 4)}
Domain = {1, 4, 9, 16} Range = {1, 1, 2, 2, 3, 3, 4, 4}
