Solution:

Here,
R = {(2, 4), (3, 6), (4, 8), (5, 10)}

∴ R−1 = {(4, 2), (6, 3), (8, 4), (10, 5)}

Solution:

Here,
R = {(a, w), (b, x), (c, y), (d, z)}

∴ R−1 = {(w, a), (x, b), (y, c), (z, d)}

Solution:

Here,
R = {(1, 3), (5, 7), (9, 11), (13, 15)}

∴ R−1 = {(3, 1), (7, 5), (11, 9), (15, 13)}

Solution:

Here,
R = {(p, a), (q, b), (r, c), (s, d)}

∴ R−1= {(a, p), (b, q), (c, r), (d, s)}

Solution:

Here,
R = {(1, 2), (1, 4), (2, 2), (2, 4), (3, 4)}
Domain of R = a set of x-components of each ordered pair of the relation R.
= {1, 1, 2, 2, 3}
= {1, 2, ,3}

Range of R = a set of y-components of each ordered piar of the relation R.
= {2, 4, 2, 4, 4}
= {2, 4}

Solution:

Here,
Domain of R = set of x-component
= {2, 2, 2, 3, 3}
= {2, 3}

Range of R = set of y-component
= {a, b, c, a, b}
= {a, b, c}
