Let's go through each part of the problem step by step.
### 9.1 Domain of \( g \)
The function \( g(x) = \frac{6}{x+3} + \frac{3}{2} \) is undefined when the denominator is zero. Therefore, we set the denominator equal to zero:
\[
x + 3 = 0 \implies x = -3
\]
Thus, the domain of \( g \) is all real numbers except \( -3 \):
\[
\text{Domain of } g: \{ x \in \mathbb{R} \mid x \neq -3 \}
\]
### 9.3 Shifting the graph of \( g \) to coincide with \( h \)
The functions are:
\[
g(x) = \frac{6}{x+3} + \frac{3}{2}
\]
\[
h(x) = \frac{6}{x-3} + 2
\]
#### 9.3.1 Horizontal Shift
To find the horizontal shift, we need to determine how to transform \( g(x) \) into \( h(x) \). The term \( x+3 \) in \( g(x) \) must be changed to \( x-3 \) in \( h(x) \).
To achieve this, we can set:
\[
x + 3 = x' - 3 \implies x' = x + 6
\]
Thus, the graph of \( g \) must be shifted **6 units to the left**.
#### 9.3.2 Vertical Shift
Next, we look at the vertical shift. The constant term in \( g(x) \) is \( \frac{3}{2} \) and in \( h(x) \) it is \( 2 \).
To find the vertical shift, we calculate:
\[
2 - \frac{3}{2} = \frac{4}{2} - \frac{3}{2} = \frac{1}{2}
\]
Thus, the graph of \( g \) must be shifted **upward by \( \frac{1}{2} \)**.
### 9.4 Asymptotes of \( g \)
The vertical asymptote occurs where the denominator is zero:
\[
x + 3 = 0 \implies x = -3
\]
The horizontal asymptote can be found by considering the behavior of \( g(x) \) as \( x \to \infty \):
\[
\lim_{x \to \infty} g(x) = \lim_{x \to \infty} \left( \frac{6}{x+3} + \frac{3}{2} \right) = 0 + \frac{3}{2} = \frac{3}{2}
\]
Thus, the equations of the asymptotes of \( g \) are:
- Vertical asymptote: \( x = -3 \)
- Horizontal asymptote: \( y = \frac{3}{2} \)
### 9.5 \( x \)-intercept of \( g \)
To find the \( x \)-intercept, we set \( g(x) = 0 \):
\[
\frac{6}{x+3} + \frac{3}{2} = 0
\]
Solving for \( x \):
\[
\frac{6}{x+3} = -\frac{3}{2}
\]
Cross-multiplying gives:
\[
6 \cdot 2 = -3(x + 3) \implies 12 = -3x - 9 \implies 3x = -21 \implies x = -7
\]
Thus, the \( x \)-intercept of \( g \) is \( (-7, 0) \).
### 9.6 Sketch of the graph of \( g \)
To sketch the graph, plot the vertical asymptote at \( x = -3 \), the horizontal asymptote at \( y = \frac{3}{2} \), and the \( x \)-intercept at \( (-7, 0) \). The graph will approach the asymptotes and will have a hyperbolic shape.
### 9.7 Value of \( k \) for axis of symmetry
The axis of symmetry \( h(x) = -x + k \) must satisfy the condition that \( g(x) \) is symmetric about this line. The line \( y = -x + k \) has a slope of -1, which means it is a diagonal line.
To find \( k \), we need the midpoint of the points \( (x, g(x)) \
