Look at the following graphs. Notice that there are odd$-$degree vertices. Identify the odd$-$

degree vertices by coloring the "circles" in with, say, a red pen or just making a nice, solid dot.

See if you can duplicate existing edges and make all the vertices of even degree. Draw your new

graphs and upload a photo or document with them in Canvas under the Graphing exploration $3$

assignment. How to identify odd degree vertices in a graph
