$$f = (\lnot x \land \lnot y)\lor (x \land y),$$
using \textit{variable order} $z < x < y$. Use complemented edges and a node for \texttt{true} as the only constant node. To simplify drawing, you may assume that \textit{dangling edges} point to the constant node. Write down all cofactors that you compute to obtain the final result and mark them in the graph.
