(a) Let a, b, c, d, e and f be
(i)
Consider the set D = {1, 2, 3, a, b, c, d, e, ƒ} (with repetitions allowed).
By ordering your set from smallest to largest, including repetitions,
state whether or not the resulting sequence is the degree sequence of
a graph. Justify your answer.
(ii) If necessary, by adjusting just one of the terms in your sequence
from part (i), draw a graph whose degree sequence is made from your
new sequence.
(iii) Is the graph you constructed in part (ii) simple? Justify your answer.
