Find the local maximum and minimum values of y= (x)/(xsquared + 4) by using the first and second derivatives.

OpenStudy (anonymous):

Take the first derivative of y and set it equal to zero; solve for x and you have your possible minima and maxima. If you take the second derivative, plug in the points you just for, and your value is negative, then you have a maximum at that point. If the second derivative at that point is positive, then you have a minimum.
