WebOn the other hand, if a function has the set of integers as its domain, we're dealing with a discrete structure. If you graph the function f defined by f(n) = n, where n is an integer, it looks like a diagonal line passing through the origin, but instead of a straight line, it's a set of points. Going back, this function f is f: Z ----> Z.
