Answer

Explanation:

Step1: Determine symmetry

For a function (y = f(x)=\frac{2x}{x^{2}-16}), check (f(-x)). [ \begin{align*} f(-x)&=\frac{2(-x)}{(-x)^{2}-16}\ &=\frac{- 2x}{x^{2}-16}\ &=-f(x) \end{align*} ] Since (f(-x)=-f(x)), the function is odd. Odd - functions are symmetric about the origin.

Step2: Find the derivative (y') using the quotient rule

If (y = \frac{u}{v}) where (u = 2x) and (v=x^{2}-16), the quotient rule states that (y'=\frac{u'v - uv'}{v^{2}})

  • (u'=\frac{d}{dx}(2x)=2)
  • (v'=\frac{d}{dx}(x^{2}-16)=2x)

[ \begin{align*} y'&=\frac{2(x^{2}-16)-2x(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*} ]

Answer:

The function is an odd function that is symmetric about the origin (Option D). The derivative (y'=\frac{-2(x^{2}+16)}{(x^{2}-16)^{2}})
