Question

13. Given the graph
List all the even vertices. Please see atachment.

Answer 1

nothing appears on my screen

Answer 2

I just opend it. so it does work.

Answer 3

it opens for you, but not for me ....

Answer 4

you don't have adobe 9 on your computer?

Answer 5

prolly not, its a public library computer...

Answer 6

ah

Answer 7

try now

Answer 8

that one works :)

Answer 9

now just have to determine what constitutes an 'even' vertice

Answer 10

ok. this is where i don't understand

Answer 11

me either yet, i think it means that the degree of the vertex is an even number, but gotta read a little more

Answer 12

is this all the information that is given?

Answer 13

vertices with even degree are even vertices, also those where a loop exists

Answer 14

how can you determine an even degree vertice with no numbers present?

Answer 15

A, B, D and E

Answer 16

no of edges leaving a vertex is the degree

Answer 17

its an undirected graph

Answer 18

what do you mean uzma

Answer 19

ahhh... so three lines connected is an odd then right?

Answer 20

yes

Answer 21

look ...there is a loop at vertex A, a loop contributes 2 to the degree, so A is an even vertex

Answer 22

so then it woud be A B D and E like you said then?

Answer 23

likewise there r 2 edges incident at B,degree 2 again even

Answer 24

yeah

Answer 25

ok. i get it now thank you.
