    1. The domain set of C = { (2,5), (2,6), (2,7) } is the set of all first elements of the ordered pairs.

    Therefore, domain set of C = {2}

    2. The range set of E = { (3, 3), (4, 4), (5, 5), (6, 6) } is the set of all second elements of the ordered pairs.

    Therefore, range set of E = {3,4,5,6}

    3. We need to find the range and domain of F = x + y = 10.

    Clearly, the domain is the set of all real numbers.

    Also, if x is a real number, then 10 - x is also a real number.

    We have, x + y = 10

    y = 10 - x

    So, y is also a real number.

    Therefore, range and domain of F = {all real numbers}

    4. We need to find the range and domain of P = y = 3.

    Clearly, the domain is the set of all real numbers.

    Since, the y = 3 (the second element of the ordered pair), the range is the singleton set {2}.

    Hence, domain = {all real numbers} and range = {y : y = 3}

    the domain set of C = { (2, 5), (2, 6), (2, 7) } = {2}

    the range set of E = { (3, 3), (4, 4), (5, 5), (6, 6) } = {3, 4, 5, 6}

    the range and domain of F = (x, y) = domain = range = {all real numbers}

    the range and domain of P = y = 3 = domain = {all real numbers}: range = {y: y = 3}
