PLEASE ANSWER ALL PARTS OF THIS QUESTION.

For the following directed graph, let ? = {?,?,?, ?, ?} and let ? = {?, ?, ?, ?}.

For the definition of ? below, determine if ? is a function. If it is a function, state its domain and codomain in the form “?:? → ?” and give a table of values that lists each element ? of the domain along with the corresponding element ��(?) of the codomain. If the given ? is not a function, explain why not.

If ? is a vertex, then ?(?) is the indegree of ?.
