Problem

Consider the function g(x)=xsin⁡(1/x)g(x)=x\sin\bigl(1/x\bigr) on the open interval (0,1)(0,1). The function is not defined at x=0x=0, and we do not extend its definition to that point. (a) Determine whether gg is bounded on (0,1)(0,1). Support your answer with reasoning. (b) Decide whether the Extreme Value Theorem guarantees the existence of an absolute maximum or minimum of gg on (0,1)(0,1). Provide a complete justification. (c) Evaluate lim⁡x→0+g(x)\displaystyle \lim_{x\to 0^{+}} g(x) and explain how this limit informs your conclusion in part (b). (d) State whether gg actually attains an absolute maximum or absolute minimum value on (0,1)(0,1). Justify your answer thoroughly.
