I'm having trouble with reciprocal functions. If a graph of a reciprocal function is given, how do you find its equation? Any help would be really appreciated.

1. On the same graph, measure y values at a many of x value (at least 10), and make a new plot of 1/y vs x. That will be the reciprocal function. Draw a smooth crve though the points. It is different from the inverse function.
