WebA function ${f}:{A}\to{B}$ is said to be one-to-one if \[f(x_1) = f(x_2) \Rightarrow x_1=x_2\] for all elements $x_1,x_2\in A$. A one-to-one function is also called an … WebOne-to-one Functions. If a function has no two ordered pairs with different first coordinates and the same second coordinate, then the function is called one-to-one.

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. immokalee high school bell scheduleWebStefania Costantini.
