Aug 9, 2019 · Then the range is 0<f (x)<20. But you can't say that the codomain of f is 0<f (x)<20, because you totally can get a value higher than 20 if you get a different domain. So the range is …

Aug 24, 2011 · I'm a little confused between the difference between the range & co-domain of a function. Are they not the same thing (i.e. all possible outputs of the function)?

This doesn't make sense if range and image aren't the same thing, so I'm just wanting to be completely sure. Furthermore, does codomain refer to the image of the transformation or to the vector space to …

The image of the whole domain is called the range of the function. Then what exactly is the difference between the range of a function and the target of a function?

Apr 18, 2016 · It is best to avoid the word "range" since it means different things to different people. So better to ask: "How are image and pre-image different from codomain and domain respectively" or …

That set is called column space of the matrix A or its range. And those linear independent columns of matrix form basis for this range, or are called to "span the column space" of matrix A. Did I …

The preimage of the range of the function (not to be confused with the codomain, which is usually just $\mathbb {R}$) is indeed the domain; and the preimage of some proper subset of the range would be …
