Let \( f:\mathbb{R}\to \mathbb{R} \) be a function defined by
Then which of the following statements is TRUE?
Let \( \mathbb{R} \) denote the set of all real numbers. Let \( f:\mathbb{R}\to\mathbb{R} \) and \( g:\mathbb{R}\to(0,4) \) be functions defined by \( f(x)=\log_e\!\left(x^2+2x+4\right) \), and \( g(x)=\dfrac{4}{1+e^{-2x}} \). Define the composite function \( f\circ g^{-1} \) by \( (f\circ g^{-1})(x)=f\!\left(g^{-1}(x)\right) \), where \( g^{-1} \) is the inverse of the function \( g \).
Then the value of the derivative of the composite function \( f\circ g^{-1} \) at \( x=2 \) is ___________.
