WebTo check if the function is onto, try to solve the equation 2 x + y = z for arbitrary z (one solution is enough). To check if the function is one-to-one, check if 2 x 1 + y 1 = 2 x 2 + y 2 implies x 1 = x 2 and y 1 = y 2. Thanks Yuval Filmus! I've found that it is both 1-1 and onto.

Webcorrespondence or bijection if it is both one-to-one and onto. Notice that “f is one-to-one” is asserting uniqueness, while “f is onto” is asserting existence. This gives us the idea of how to prove that functions are one-to-one and how to prove they are onto. Example 1. Show that the function f : R → R given by f(x) = 2x+1 is one-to ...
