The domain the region in the real line where it is valid to work with the function $$f(x)$$, in terms of the values that $$x$$ can take. We need to see where the function is well defined. Let’s start with the domain. Well in a rational expression, you have to look at the denominator, because if a value is put in the denominator and it makes it 0 then it will go to infinite, so you have to solve the denominator and find the values that makes it 0, and in the domain you have to specify any value of the Reals except those values that makes it 0, of course in the proper notation.
