Use induction to prove that for every integer n, the number n³-n is an integer.
(Note that you're asked to prove this for every integer, not just the positive integers. Induction is
a very helpful tool here, but a standard induction proof alone won't get the job done without some
modification or some additional work.)

{x = R
x>0},
Before stating the next problem, we need to make some definitions. We write I
and say that a function ƒ : I → I is strictly increasing if Vx, y Є I with x > y we have f(x) > f(y).
