How do i do this?

For the graph below: (a) Find all edges incident on upsilon_1. (b) Find all vertices that are adjacent to upsilon_3. (c) Find all edges that are adjacent to e_1. (d) Find all loops. (e) Find all parallel edges. (f) Find all isolated vertices. (g) Find deg(upsilon_3). (h) Find deg(Gamma).

Solution

(a) e1

(b) v1 and v2

(c) v1

(d) v1e1, v2e3 , v5e4v2e5, v1e2v2v3e7

(e) e4e5
