**Problem Description:**

For the following directed graph, let \( E = \{I, J, K, L, M\} \) and let \( V = \{a, b, c, d\} \).

[Directed Graph Explanation]:
- The graph consists of 5 edges: \( I, J, K, L, M \).
- Vertices in the graph are labeled as \( a, b, c, d \).
- Edges are directed as follows:
  - \( I: \) from \( a \) to \( d \)
  - \( J: \) from \( a \) to \( b \)
  - \( K: \) from \( b \) to \( c \)
  - \( L: \) from \( c \) to \( d \)
  - \( M: \) from \( a \) to \( c \)

**Task:**

For each definition of \( f \) below, determine if \( f \) is a function. If it is a function, state its domain and codomain in the form \( "f: X \to Y" \) and provide a table of values that lists each element \( x \) of the domain along with the corresponding element \( f(x) \) of the codomain. If the given \( f \) is not a function, explain why not.
