The domain of function f is the interval 0. Identify the domain of a logarithmic function The domain of y is displaystyle left -infty infty right. You will come up with an error.

When finding the domain of a logarithmic function therefore it is important to remember that the domain consists only of positive real numbers. G x 0. We first start with the properties of the graph of the basic logarithmic function of base a f x log a x a 0 and a not equal to 1.

F x log -3x The domain of f x is Type your answer in interval notation. Determine the transformations applied to. There are 2 other rules.

So the domain is the set of all positive real numbers. Graph the parent function. The logarithmic function y log bx can be shifted k units vertically and h units horizontally with the equation y log bxhk.
