    {7, 11, 15, 19}

    Step-by-step explanation:

    The function is defined by the formula y = 2x + 1 ... (1)

    Now, domain of the function are given to be {3, 5, 7, 9}

    Hence, from equation (1), at x = 3, y = 2 * 3 + 1 = 7

    Now, at x = 5, y = 2 * 5 + 1 = 11

    Again, at x = 7, y = 2 * 7 + 1 = 15

    Finally, at x = 9, y = 2 * 9 + 1 = 19

    Therefore, the range of the corresponding domain of this function is given to be {7, 11, 15, 19}. (Answer)
