The function $f : \mathbb{R} \rightarrow \textsuperscript{+}\mathbb{Z}$ . This tells me that I have defined a function f such that f maps the elements from the set of natural numbers to elements of the integers.

Let’s give an arbitrary function $$f$$ such that $$f$$ maps elements from set $$A$$ to set $$B$$. The graph of this function is defined by… $$R_f = {\left \{ \left \langle x,y \right \rangle : f(x) = y\right \}}$$
