Question: Assume f: R R is a function. We say that f is increasing if *>y implies that f(x) > f(y), for any r, y
Assume f: R R is a function. We say that f is increasing if *>y implies that f(x) > f(y), for any r, y R. Below are two conjectures. For each, either prove they are true or find a counterexample. (a) Conjecture 1: If f: R R is an increasing function, then f is injective. (b) Conjecture 2: If f: R R is an increasing function, then f is surjective.
