Function Division 8Cde0A
1. **Problem:** Given $f(x) = 3x - 3$ and $g(x) = \frac{2}{x-1}$, find $\left(\frac{f}{g} - 2f(3)\right)$.
2. **Step 1:** Calculate $f(3)$.
$$f(3) = 3(3) - 3 = 9 - 3 = 6$$
3. **Step 2:** Write the expression $\frac{f}{g} - 2f(3)$ explicitly.
$$\frac{f(x)}{g(x)} - 2f(3) = \frac{3x - 3}{\frac{2}{x-1}} - 2 \times 6 = \frac{3x - 3}{\frac{2}{x-1}} - 12$$
4. **Step 3:** Simplify the fraction division.
$$\frac{3x - 3}{\frac{2}{x-1}} = (3x - 3) \times \frac{x-1}{2} = \frac{(3x - 3)(x-1)}{2}$$
5. **Step 4:** Factor $3x - 3$ as $3(x-1)$.
$$\frac{3(x-1)(x-1)}{2} = \frac{3(x-1)^2}{2}$$
6. **Step 5:** Substitute back into the expression.
$$\frac{3(x-1)^2}{2} - 12$$
7. **Step 6:** Evaluate at a convenient $x$ to find the value of the expression. Since the problem does not specify $x$, assume $x=3$ (used in $f(3)$).
$$\frac{3(3-1)^2}{2} - 12 = \frac{3(2)^2}{2} - 12 = \frac{3 \times 4}{2} - 12 = \frac{12}{2} - 12 = 6 - 12 = -6$$
**Answer:** $-6$ which corresponds to option A.
