Finding the domain of a logarithmic function
WebA function which varies for different parts of the domain, so the domain is divided into segments, and each segment could have a different function. One of common ones is stair step function with domain 0≤x<1 y=1. 1≤x<2 y=2, 2≤x<3 y=3, etc. which looks like a stair step without the vertical components.

The domain can also be given explicitly. Examples on How to Find the Domain of logarithmic Functions with Solutions Example 1 Find the domain of function f defined by f (x) = log3(x - 1) Solution to Example 1f(x) can take real values if the argument of log3(x - 1) which is x - 1 is positive. WebWhen finding the domain of a logarithmic function, therefore, it is important to remember that the domain consists only of positive real numbers. That is, the argument of the logarithmic function must be greater than zero. For example, consider f(x) = log4(2x − 3).

WebThe basic property of a log of a number that is not positve is this: Let k > 0. The log's base is, of course, e. log (−k) = log k + π 𝑖 log (-k 𝑖) = log k − ½ π 𝑖 That isn't too hard, but when you start working with full complex numbers such as Log (3 + 4𝑖) it can get very tricky (getting into something called branches and branch cuts).
