The subset of elements in Y that are actually associated with an x in X is called the range of f. Since in this video, f is invertible, every element in Y has an associated x, so the range is actually equal to the co-domain. So yes, Y is the co-domain as well as the range of f and you can call it by either name.

f'(g(x)) = f'(y) = 1 / g'(x) with a catch: the names like x, y, f(x), g(x), inverse, and d/dx are just names for human conveneince. thus, if you want to really understand a concept like this one to the bottom, better not give a heavy weight on a specific name. thus, your asking of a graphical understanding is quite reasonable and helpful not ...Web3 Similarly, the marginaltpdf of X is f X (x) = ! fX,Y(x,y)dy Note: When X or Y is discrete, the corresponding integral becomes a sum. 4 Join andConditional Distributions :What is the difference between f (x) and y?
