Many of my algebra and precalculus students think the 'inverse function' of f(x), often written f^(-1)(x), is the same as the reciprocal 1/f(x) (mistaking the -1 for an exponent). This (as I am obliged to remind them) is almost always false. But can you find at least one function whose inverse is also its reciprocal? Tiebreaker: Find as many as you can!

Lajwanti of village Lajpur was a young, demure, and lively woman. Sarita, her neighbor, asked her once, on seeing her with a gentleman, "What is your relationship with the gentleman who accompanied you?" Lajwanti replied, "I will neither tell you his name nor my relations with him. I will, however, reveal that his mother-in-law and my mother-in-law are mother and daughter." How were these two related to each other?
