Answer

Explanation:

Step1: Find the first derivative (y')

Use the quotient rule ((\frac{u}{v})'=\frac{u'v - uv'}{v^{2}}), where (u = 2x), (u'=2), (v=x^{2}-16), (v' = 2x). [ \begin{align*} y'&=\frac{2(x^{2}-16)-2x\times(2x)}{(x^{2}-16)^{2}}\ &=\frac{2x^{2}-32 - 4x^{2}}{(x^{2}-16)^{2}}\ &=\frac{-2x^{2}-32}{(x^{2}-16)^{2}}\ &=\frac{-2(x^{2}+16)}{(x^{2}-16)^{2}} \end{align*} ] Since (x^{2}+16>0) and ((x^{2}-16)^{2}>0) for all (x\neq\pm4), (y'<0) for all (x\neq\pm4).

Step2: Analyze critical points

Critical points occur where (y' = 0) or (y') is undefined. (y') is never (0) (because (-2(x^{2}+16)\neq0) for all real (x)), and (y') is undefined at (x = 4) and (x=-4) (but these are not in the domain of the original function (y=\frac{2x}{x^{2}-16}), domain is (x\in(-\infty,-4)\cup(-4,4)\cup(4,\infty))).

Since the function is always decreasing (because (y'<0) on its domain), there are no local maxima or minima.

Answer:

B. There are no local minima. B. There are no local maxima.
