Converting implicit function to explicit

Click For Summary
SUMMARY

The discussion centers on the conversion of an implicit function, specifically the equation x + ln(y)/y² = 0, into an explicit function of the form y = f(x). Participants assert that while converting to an explicit function may not be feasible under certain conditions, expressing the function as x = g(y) remains a valid approach. The conversation highlights the limitations of implicit functions and the mathematical techniques involved in such conversions.

I have an implicit function [e.g. [itex]x+\frac{ln(y)}{y^2}=0[/itex])]. Is there any mathematical trick/technique that can convert this to an explicit function (i.e. [itex]y=f(x)[/itex]) even within certain restrictions and conditions.

I don't believe so. It would be simple to write as x = g(y), though. What's wrong with that?
