1. The problem statement, all variables and given/known data Find the equations that satisfy the following properties: 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). 2. Relevant equations 3. The attempt at a solution I'm thinking that i need to use a trig function for number 1, but beyond that i'm stumped.
