    Answer:

    Domain = x > 2 , Range = {R}

    Step-by-step explanation:

    The given function to us is ,

    \implies f(x) = log_{10} ( x - 2 ) + 1

    Since logarithm are defined only for positive numbers therefore ,

    => (x – 2) > 0

    => x > 2

    Therefore the domain of the function is x > 2 and it can have all positive real numbers .
