Let $f(x) = 2x + \tan^{-1} x$ and $g(x) = \log_e\left(\sqrt{1 + x^2} + x\right)$, $x \in [0, 3]$. Then\\
(1) There exists $x \in (0, 3)$ such that $f'(x) < g'(x)$\\
(2) $\max f(x) > \max g(x)$\\
(3) There exist $0 < x_1 < x_2 < 3$ such that $f(x) < g(x)$, $\forall x \in (x_1, x_2)$\\
(4) $\min f'(x) = 1 + \max g'(x)$
