Sep 1, 2015 · To find domain of a function, $f (x)$, find for what values of $x$, $f (x)$ will be undefined/not real. To find range, the general method is to find $x$ in terms of $f (x)$ and then find …

Oct 20, 2021 · I can understand what the range is by looking at the graph however I don't know how to find this algebraically. Is there a method that I can use every time to get the range? Also I know there …

Is there a common way to denote the domain or range of a function? I've seen things like $ \cal {D}\left (f\right) $ and $ \cal {R}\left (f\right) $ for the domain and range, respectively, but I wasn't sure if there …

Aug 9, 2019 · When a function is defined, you get to pick your domain and codomain, so the codomain may consist of elements that are not an image of any elements in the domain. The range is all the …

Jun 30, 2019 · Can someone please explain to me in layman what each means? Perhaps with some examples with functions (inputs to outputs/numeric values in them)? Especially range, image, and …

Apr 13, 2015 · What will be the range of function $y=(e^x-e^{-x})/(e^x+e^{-x})$ ? How should I approach this category of problems with exponential functions? Please Help.

The outputs a particular function actually uses from the set of all Reals is the image, also sometimes called the range. Thus, what could come out of a function is the codomain, but what actually comes …

Dec 13, 2016 · An unsophisticated question from a neophyte: Given the numbers: $1,2,3,4,5$ What is the symbol for the range of the numbers? i.e. the lowest-highest number in the set. For example, the …

Feb 8, 2021 · The set of allowed input values is called the domain of the function. A common way to specify a function is by giving a domain and some algebraic formula for computing the output. In your …

Nov 14, 2013 · The range is always a subset of the codomain: it’s the set of values that the function actually assumes (or if you prefer — and in CS you might! — outputs).
