    You have to find when the function is undefined or doesn't produce real numbers to find the domain. The range is a bit trickier, but another method is to use the graph of the function

    to find the domain , you need to find what cant be an input and exclude that from the real numbers, to find the range take the inverse of the function and do the same thing to the inverse

    it is really a lot easier to answer a question like this with a specific example. it depends almost entirely on the given function

    for example, if you have a trigonometric function like \(\sin(x)\) whose domain is all real numbers and whose range is \([-1,1]\) you have to know something about the function to start even more so with a function like \(\arcsin(x)\) whose domain is \([-1,1]\) and whose range is \([-\frac{\pi}{2},\frac{\pi}{2}]\)

    correct, the way I explained was a general way that assumed the function was 1 to 1

    so there is not one mathematical method "find the domain" or "find the range" the real truth is that the domain is supposed to be part of the definition of the function to begin with, so the question "find the domain" is in fact inaccurate

    it would be much more enlightening to ask "find the domain and range of \(f(x)=\frac{x-1}{x+1}\) or something more specific

    is it applicable to each type of functions ?
