Identity Function

The functionf(x) = x. More generally, an identity function is one which does not change the domain values at all.

Note: This is called the identity function since it is the identity for composition of functions. That is, if f(x) = x and g is any function, then (f°g)(x) = g(x) and (g°f)(x) = g(x).
