Finding the domain of log functions
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). WebTo find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square …

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) f ( x) = l o g 4 ( 2 x − 3). This function is defined for any values of x such ... WebAug 16, 2015 · g ( x) = ln ( x + 2) + ln ( x + 1) Therefore, x + 1 > 0. x > − 1. And, x + 2 > 0. x > − 2. Both values on both sides of both inequalities are correct, however, in the answer, the sign is flipped for the second inequality. It will become apparent that the sign must be flipped (in the second inequality) when some numbers are inputted into the ...

WebThe domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values. When finding the domain, remember: The denominator (bottom) of a fraction cannot be zero

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.
