5. Consider the function f: defined on positive integers with f(n) = n "flipped" as a mirror image into a decimal. For example, f(5) = .5, f(418) = .814, and f(1000) = .0001. Define a relation R on the positive integers as (m, n) 6 R if and only if f(m) s f(n). For example, (5, 418) ER because .5 s .814 but (418, .923) @ R because 814 > .329. Is R a partial order? Either provide a proof to show that this is true or provide a counterexample to show that this is false. This problem is similar to examples and exercises in Section 4.4 of your SNHU MAT299 textbook
