In this question you will prove that the complete graph with n vertices Kn is the only graph on n vertices with vertex connectivity equal to n - 1. Let G be a graph with n vertices. 1. Prove that if removing n - 2 vertices from G disconnects G then the vertex connectivity of G is at most n - 2. 2. Prove that if G is not equal to Kn then the vertex connectivity of G is at most n - 2. Hint: if G# Kn then there are two vertices of G that do not have an edge between them. Note that, since Kn has vertex connectivity equal to n - 1 (you do not have to prove this), this means that it is the only graph on n vertices with vertex connectivity equal to n - 1.

Please help. Thank you

In this question you will prove that the complete graph with n vertices Kn is the only graph on n
vertices with vertex connectivity equal to n - 1.
Let G be a graph with n vertices.
1. Prove that if removing n - 2 vertices from G disconnects G then the vertex connectivity of G
is at most n - 2.
2. Prove that if G is not equal to Kn then the vertex connectivity of G is at most n — 2.
Hint: if G# Kn then there are two vertices of G that do not have an edge between them.
Note that, since Kn has vertex connectivity equal to n - - 1 (you do not have to prove this), this
means that it is the only graph on n vertices with vertex connectivity equal to n - 1.
