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

Find the domain and range of the function $latex f(x)=3\log(x-3)+4$. Solution: The 3 represents a stretch of the graph and the 4 represents a vertical translation of the graph. These two values do not affect either the domain or the range of

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
