Find the domain of function f defined by f (x) = log 3 (x - 1) Solution to Example 1 f (x) can take real values if the argument of log 3 (x - 1) which is x - 1 is positive. Hence the condition on the
Domain and Range of Log Functions Let us consider the basic (parent) common logarithmic function f (x) = log x (or y = log x). We know that log x is defined only when x > 0 (try finding log 0, log (-1), log (-2), etc using your calculator. You will
