#7
![**Precalculus 1.5**
**HW4**
**Instructions:**
Find the following:
(a) \((f + g)(x)\), (b) \((f - g)(x)\), (c) \((f \cdot g)(x)\), (d) \(\left(\frac{f}{g}\right)(x)\). What is the domain of (d)?
1) \(f(x) = 3x - 6\), \(g(x) = 3 - x\)
2) \(f(x) = \frac{x}{x - 2}\), \(g(x) = x^3 + 1\)
Evaluate the indicated function for \(f(x) = x^2 - 2\) and \(g(x) = x - 1\) algebraically.
3) \((f - g)(2)\)
4) \(\left(\frac{f}{g}\right)(t - 2)\)
Find (a) \((f \circ g)(x)\) and (b) \((g \circ f)(x)\)
5) \(f(x) = x^4 - 4\), \(g(x) = \sqrt[4]{x + 4}\)
6) \(f(x) = x^2 + 9\), \(g(x) = \sqrt{x}\)
Use the graphs of \(f\) and \(g\) to evaluate the functions:
7) (a) \((f \circ g)(1)\)
(b) \((f \circ g)(4)\)
8) (a) \((f \circ g)(1)\)
(b) \((g \circ f)(3)\)
**Graphs Description:**
- **Graph of \(f(x)\):**
- The graph shows a V-shaped curve resembling an absolute value function.
- It consists of points \((1, 2)\), \((2, 0)\), \((3, 2)\), and \((4, 3)\).
- **Graph of \(g(x)\):**
- The graph illustrates a downward-sloping linear function.
- It includes points \((1, 3)\), \((2, 2)\), \((3, 1)\), and \((4, 0)\).
Both graphs use a standard](https://content.bartleby.com/qna-images/question/7342a733-51b7-4524-8fc4-4aee8aaeea97/c545b565-1052-438c-ac5c-8dd85ef4a49a/0pcyls8_thumbnail.jpeg)
