Given the graph, determine if the following sequences form a walk, path and/or a circuit.
1. a, b, c, e
2. b, c, d, d, e, c, f
3. a, b, c, f, g, a
4. b, c, d, e
My answer:
1. It's not possible for the vertices to form a walk, path, or a circuit in this configuration. There is no relation from c to e.
2. walk
3. walk, circuit
4. walk, path
