1. The problem statement, all variables and given/known data Problem 2: Find the absolute extreme values of f(x) on the interval (1, infinity). 2. Relevant equations 3. The attempt at a solution It seems as if this is an indiscretion by the teacher. Absolute extrema don't occur on open intervals except in the case of (-∞,∞) such as in case of sin(x). Am i missing something?
