2. Consider functions f : {1, 2, 3, 4, 5, 6} → {1, 2, 3, 4, 5,
6, 7, 8, 9, 10}.
(a) How many of these functions are strictly increasing (i.e.
f(1) < f(2) < f(3) < f(4) < f(5) < f(6))? Hint: How
many different possibilities are there for the range of f? For each
range of f, how many strictly increasing functions are there?
(b) How many of these functions are non-decreasing (i.e. f(1) ≤
f(2) ≤...

3. Let X = {1, 2, 3, 4}. Let F be the set of all functions from
X to X. For any relation R on X, define a relation S on F by: for
all f, g ∈ F, f S g if and only if there exists x ∈ X so that
f(x)Rg(x).
For each of the following statements, prove or disprove the
statement.
(a) For all relations R on X, if R is reflexive then S is
reflexive....
