Question: 1. The graph GL at left in Figure is planar. How many faces does a planar drawing of GL have?
2. The graph GR at right in Figure is planar. How many faces does a planar drawing of GR have?
3. Suppose a connected planar graph P has every vertex of degree at least 3, and every face of size at least 3. Can P have fewer than six edges?
4. Suppose a connected planar graph P has every vertex of degree at least 3 and every face of size at least 3. Can P have exactly seven edges?
