Consider the following functions $f_1 : D_1 \to \mathbb{R}$ , $f_2 : D_2 \to \mathbb{R}$ , $f_3 : D_3 \to \mathbb{R}$ and $g : D \to \mathbb{R}$ , defined as:

$f_1(x) = \sin 2x$ .
$f_2(x) = \ln(x^2 - 6x + 8)$ .
$f_3(x) = e^{3x} + 5$ .
$g(x) = f_1(x) + f_2(x) + f_3(x)$ .

Let $D_1, D_2, D_3$ and $D$ be the (largest) domains of the functions $f_1(x), f_2(x), f_3(x)$ and $g(x)$ , respectively. Use this information to answer the subquestions.
