Concept explainers
Here we celebrate the power of algebra as a powerful way of finding unknown quantities by naming them, of expressing infinitely many relationships and connect ions clearly and succinctly, and of uncovering pattern and structure.
Vertex z. A drawign of a planar graph has V vertices, E edges, and F regions. Suppose you know a number z such that
Find the number of vertices, edges, and regions in your graph drawing.
