The set of consecutive integers are:

$z = \{...,-3, -2, -1, 0, +1, +2, +3,...\}$

If the function is finite, then there are two values

and

, being
$a\ \textless \ b$ , in which this function is valid, then:

f(x) = x

being

the set of integers in the interval defined by
(a,b)

If the function is infinite, the function is valid in the set of all integers then:

f(x) = x

And -∞

+∞
