Let A = {1,2,3,4} and B = {u, v, x, y, z). (a) Give an example of a function f:A-B that is one-to-one. (b) Give an example of a function 9: A - B that is not one-to-one. Let A and B be finite sets, and consider the following false statement: If |AL SBI, then every function f: AB is one-to-one. (a) Give a counterexample to illustrate that the above statement is false. Clearly specify your choice for A, B, and how you are defining your function f. (b) Explain in your own words why your counterexample from part (a) works.
