I just need b.) 

you can use a.) as an example

thank you!

**Determine the edge connectivity and the vertex connectivity of each graph.**

**(a) Graph:**

Diagram: 
- Vertices: 1, 2, 3, 4, 5, 6, 7, 8
- Edges: Connect the vertices in the following pattern:
  - 1 ↔ 2, 1 ↔ 4
  - 2 ↔ 3, 2 ↔ 6
  - 3 ↔ 4
  - 6 ↔ 7, 6 ↔ 8
  - 7 ↔ 8, 7 ↔ 5

**Solution:**

- **Vertex connectivity** is 1. The removal of vertex 6 disconnects the graph into two connected components. At least one vertex must be removed to disconnect the graph.

- **Edge connectivity** is 2. The removal of edges {1, 2} and {1, 4} disconnects vertex 1 from the rest of the graph. Removing any single edge leaves the graph connected.

**(b) Graph:**

Diagram:
- Vertices: 1, 2, 3, 4, 5, 6, 7, 8
- Edges: Connect the vertices in the following pattern:
  - 1 ↔ 3, 1 ↔ 4
  - 3 ↔ 2, 3 ↔ 7
  - 2 ↔ 4, 2 ↔ 6
  - 7 ↔ 5, 7 ↔ 8

(Note: No solution is provided in the image for graph (b).)
