Aug 9, 2019 · The difference between codomain and range is that the codomain is defined by the function, while the range is the actual output values.

Jun 30, 2019 · Perhaps with some examples with functions (inputs to outputs/numeric values in them)? Especially range, image, and preimage. So far this is my understanding: Domain is basically the input x in f(x). Codomain is what f(x) produces as an output such as y when f(x) = y. Range sounds like codomain but with some restriction?

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)?

Can't figure out the difference between them. I have read wiki article about codomains and images, but what is the difference? It seems confusing the examples part in codomain article. How can we c...

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?

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 which the images of the transformation are brought?

Range R is all values taken by the function over all the x x values of the domain. A set larger than the the range is co-domain C. Infinity is never included in D and R.

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 "How are image and pre-image different target and source respectively".

Mar 26, 2024 · The range is the set of actual values mapped to by the function, and the codomain can be equal to the range, or a superset. Note 2: The third condition can be stated as f(x) = g(x) f (x) = g (x) for all x x in the domain.

If the Domain of a function is all acceptable inputs, and the image of a function is the output, what is the point of using the word Codomain? For example, I could say the cosine function maps R...
