Graph \(\mathbb{G}(f)\) of the example function \(f: ~\mathbb{X} ~\rightarrow~ \mathbb{Y}\):
`
$$ \mathbb{G}(f) ~=~ \{ (5,10),~ (1,10),~ (3,42),~ (6,2)\} $$
`

The first component of the tuple \((x,y)\) is an \(x\) element from the domain \(\mathbb{X}\) and the second component of the tuple is an \(y\) element from the codomain \(\mathbb{Y}\). The \(x\) elements are entered on the horizontal axis and the \(y\) elements on the vertical axis. The intersection of \((x,y)\) results in a point, here \((5,10)\).
