A fixed point of a permutation f of {1, 2, . . . , n} is an i such that f(i) = i. A permutation of {1, 2, . . . , n} with no fixed points is called a derangement. Dn denotes the number of derangements of {1, 2, . . . , n}. (a) Make a list of the derangements of {1, 2, . . . , n} for n = 2 and n = 3.

all it means is function 3

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.

- hope i .

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
