    Step-by-step answer:

    The domain of log functions (any legitimate base) requires that the argument evaluates to a positive real number.

    For example, the domain of log (4x) will remain positive when x>0.

    The domain of log_4 (x+3) requires that x+3 >0, i. e. x>-3.

    Finally, the domain of log_2 (x-3) is such that x-3>0, or x>3.
