Show that if \( G \) is outerplanar (see tutorial 11 for the definition) with \( v(G) \geq 2 \) then \( e(G) \leq 2 v(G)-3 \) For \( G \) a graph, let graph is outerplanar if it is planar and has a drawing with all vertices on the boundary of the infinite face. Dr, put differently, there is a drawing with all the vertices on a circle and all edges (do not intersect and) stay nside the circle.
