MathLiveImage of a function
The image (range) of a function is the set of all output values f(x) obtained as x runs over the domain of f. It is a subset of the codomain and is used to describe which values a function actually attains.
\operatorname{ran} f = \{f(x) \mid x \in \operatorname{dom} f\}What the symbols mean
| the image (range) of the function f | |

| the output of f at input x |
