\( f(x)=x\times \exp (\frac{4x+2}{x^{2}+2})\frac{d}{dx}(x) \)

Did you know that the function you're analyzing has roots in exponential growth concepts? The presence of the exponential function, \( \exp \), often represents natural growth processes in fields like biology and finance. The term \( x \times \exp\left(\frac{4x+2}{x^{2}+2}\right) \) suggests that this function could model scenarios like population dynamics or compound interest, where growth is influenced by both the underlying variable \( x \) and the exponential factor. When it comes to derivatives, a common mistake is forgetting the product rule when differentiating a function that’s a product of two components. For your specific function, remember that you need to apply the product rule, which states: \( (uv)' = u'v + uv' \), where \( u = x \) and \( v = \exp\left(\frac{4x+2}{x^{2}+2}\right) \). This can save you from miscalculations as you explore the behavior of your function!
