    Answer:

    The domain of the function are values of x that respect the following condition: x \geq 7

    Step-by-step explanation:

    We are given the following function:

    f(x) = \sqrt{x - 7}

    Domain of the square root function:

    The square root does not exist for negative values, so the domain of a square root function:

    g(x) = \sqrt{h(x)}

    Is h(x) \geq 0

    In this question:

    f(x) = \sqrt{x - 7}

    Then:

    h(x) = x - 7

    x - 7 \geq 0

    x \geq 7

    The domain of the function are values of x that respect the following condition: x \geq 7
