analysis - Give an example of a function f:[a,b]mathbbR that is continuous...


Give an example of a function f:[a,b]R that is continuous, and a sequence (f(xn)) converging to sup, but for which (x_n) does not converge.




I am having trouble coming up with an example, especially one that converges to \sup. Any and all help appreciated. Thanks!
