 In this video, we provide the solution to question number 11 for practice exam number two for math 1030, in which case we have to draw the illustration of a digraph given the following information. We have five vertices, A, B, C, D, E. I'm just gonna draw them in a pentagonal shape, just orienting around like a circle. And for the sake of it, I'll go clockwise here, A, B, C, D, and E. And so now we're gonna draw the arcs between them. These are arcs as opposed to edges. That is, there's arrows. So you do make sure you include arrowheads here. So there's an arc from A to B. I'm gonna draw an arrow like that. There's an arc from A to D. So you get that one there. Don't forget the arrowheads, that is necessary here. From B to C, you get that one. You get from one from B to E. Then you're gonna get one from C to A. So notice the direction there, it goes from C to A. Then you're gonna go from C to B. So it actually goes in both directions. So you kind of have to draw both of them there. You don't wanna go from C to C, so there's like a loop there. All right, I'm gonna handle that. Then you get one from D to E. You get one from E to A, like so. And then you get one from E to C. I don't wanna get it too messy, so I'm just gonna draw it like that. All right, and so that then gives us the graph, the diagram we're looking for. You could have drawn it a little bit differently, but the critical ingredients, you have to have the five vertices and you have to have how many are there? One, two, three, four, five, six, seven, eight, nine, 10 arcs. And the arc arrowheads are important, you need to have them. And in this case, you have arcs going in both directions, so you include both of those as well.
