Here are two new definitions about graphs. The distance between two vertices in a graph is the number o edges in a shortest path connecting them. The diameter of a graph is the greatest distance between any pair of vertices in the graph. 1. What is the diameter of the cycle C13? What is the diameter of the cycle C14? 2. What is the diameter of the path Pg? 3. What is the diameter of the compelte graph K4? 4. What is the diameter of the complete bipartite graph K3,4?

Give an example (by drawing a picture) of a connected simple graph with five vertices and six edges

7- A student has created a plot of y(t)=t^2. He needs to show another graph of z(t)=t^3 in the same plot. But every time he hits the plot() function- MATLAB generates a plot of z(t) vs t but on a different window. What is the error? O It is not possible to plot multiple plots O He is not using the line function Maybe he is using polar() instead of plot() O He is not using the hold function

Proove the following; The upper bound on the number of articulation points in a graph is the number of biconnected components minus 1
