\imageofThe \imageof command in LaTeX is used to denote the image of a set under a given function. In mathematical terms, if you have a function f: X -> Y and a subset A of X, the image of A under f is the set of all elements in Y that are mapped to by elements of A. It is often used in set theory and functions to describe the output set of a function given an input set.
Denotes the image of a function f.
\imageof fRepresents the image of set A under the function f.
\imageof(A) = \{ f(x) \mid x \in A \}Describes the image of a function f from set X to set Y.
