**Problem 2:** Let \( G \) and \( H \) be the graphs below. For each graph, determine whether it is bipartite. If the graph is bipartite, determine whether it has a perfect matching. Justify your answer.

**Graph \( G \):**

- **Vertices**: \( c, i, b, e, d, g, f \)
- **Edges**: The connections between vertices are as follows:
  - \( c \) is connected to \( g \) and \( i \).
  - \( i \) is connected to \( b \) and \( e \).
  - \( e \) is connected to \( f \).
  - \( d \) has edges connecting to \( c \), \( e \), and \( g \).
  - \( g \) is also connected to \( f \).
  
The graph forms a structure where edges create interconnected pathways among seven vertices.

**Graph \( H \):**

- **Vertices**: \( b, a, j, g, f, d, c, i, e, h \)
- **Edges**: The connections between vertices are as follows:
  - \( b \) is connected to \( g \) and \( a \).
  - \( a \) is connected to \( j \).
  - \( j \) is connected to \( g \) and \( h \).
  - \( h \) is connected to \( c \).
  - \( g \) connects \( i \), which also connects to \( c \).
  - \( f \) is connected to \( e \).
  - \( d \) connects to \( b, c, \) and \( i \).

The graph demonstrates a more complex network with multiple connections forming paths and cycles between ten vertices.
