What are the critical points for f(x) = x/(1 + x^2)?

Find the critical points, determine their nature (maxima, minima, inflection, etc.) and sketch the function: f(x) = x/(1 + x^2)

Solution Summary

This solution shows formatted calculations for the critical points and explains how this information is applied to draw the graph of the function. The graph is included as well. This solution is presented in an attached Word document.
