Question

The arrow diagram given below shows a relation R from P to Q. Write the relation in roster form, set-builder form. Find its domain and range.

Answer 1

R – {(9, -3), (9, 3), (4, -2), (4, 2), (25, -5), (25, 5)}

R = {{x, y) : y² = x}

Domain of R = {9, 4, 25}

Range of R = {5, 3, 2, -2, -3, -5
