![**Problem Statement:**
If \( g(x) = 3x - 5 \) and \( h(x) = (f \circ g)(x) = 9x^2 - 30x + 25 \), then \( f(x) = \boxed{3x - 5} \ \textcolor{red}{\text{✘}} \).
**Objective:**
Using \( g(x) \) and \( f(x) \), determine \( (g \circ f)(x) \).
\( (g \circ f)(x) = \boxed{9x - 20} \ \textcolor{red}{\text{✘}} \).
**Explanation:**
1. **Function Definitions:**
- \( g(x) \) is defined as \( 3x - 5 \).
- The composition of functions \( h(x) = (f \circ g)(x) \) is given as a quadratic expression \( 9x^2 - 30x + 25 \).
2. **Incorrect Solutions Identified:**
- The proposed solution for \( f(x) \) was incorrectly stated as \( 3x - 5 \).
- The solution for \( (g \circ f)(x) \) was incorrectly determined to be \( 9x - 20 \).
This exercise explores the errors made in finding the correct composite functions. Understanding how to correctly compute compositions is crucial for various applications in mathematics.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F96a3ec80-5465-459b-a6f3-94e5b259c9d4%2F2fbd5e9f-7ab2-445d-964a-defe4555beea%2Fm55gnld_processed.png&w=3840&q=75)

![**How to Transform the Graph of \( g(x) = \frac{13}{14} |x - 6| + 3 \) from \( f(x) = |x| \):**
1. **Horizontal Shift:**
- The graph of \( g(x) \) is obtained by shifting the graph of \( f(x) \) 6 units to the **right**.
2. **Reflection:**
- The graph of \( g(x) \) **is not** a reflection of the graph of \( f(x) \) about the x-axis.
3. **Vertical Shrink/Stretch:**
- The graph of \( g(x) \) is the graph of \( f(x) \) **shrunk** by a factor of \( \frac{13}{14} \).
4. **Vertical Shift:**
