    Range : {11,13,17,25}

    Step-by-step explanation:

    Given

    f (x) = 2x+7

    and

    Domain = {2,3,5,9}

    To find the range, the values in domain will be put in the function one by one

    So,

    f (2) = 2 (2) + 7 = 4+7 = 11

    f (3) = 2 (3) + 7 = 6+7 = 13

    f (5) = 2 (5) + 7 = 10+7 = 17

    f (9) = 2 (9) + 7 = 18+7 = 25

    Therefore the range is {11,13,17,25} ...
