Item 4.1.5.a.
Let \(f:G_1 \rightarrow G_2\) be a function that takes the vertices of Graph 1 to vertices of Graph 2. The function is given by the following table:
| \(x\) | \(a\) | \(b\) | \(c\) | \(d\) | \(e\) | \(f\) | \(g\) |
| \(f(x)\) | \(v_4\) | \(v_5\) | \(v_1\) | \(v_6\) | \(v_2\) | \(v_3\) | \(v_7\) |
Does \(f\) define an isomorphism between Graph 1 and Graph 2?
