Consider the graph with vertex set (A, B, C, X, Y, Z) and edge list AB, AC, AX, BB, BZ, CX, XZ, YY. Without drawing a picture of the graph, answer parts (a) through (d) (a) List all the vertices adjacent to B (b) List all the edges adjacent to AB (c) Find the degree of B (d) Find the sum of the degree of the vertices (a) List the vertices that are adjacent to B Use a comma to separate answers as needed) REED
