Can anybody think of equations that satisfy the following properties:(adsbygoogle = window.adsbygoogle || []).push({});

1) f:(0,infinity) -> R is continuous and bounded, but f has no maximum and no minimum (that is global min and max).

2) k:[0,infinity) -> R is continuous, but k has no maximum and no minimum (again global min and max).
