Graph Translations
1. **State the problem:**
Given the function $f(x)$ defined by the piecewise points from the graph:
- Segment 1 from $(−9,4)$ to $(−5,−1)$
- Segment 2 from $(−5,−1)$ to $(0,−9)$
- Segment 3 from $(0,−9)$ to $(3,1)$
We need to find values for:
- Table 1: $f(x) + 2$ for $x = -5, 0, 3, -9$
- Table 2: $f(x) - 2$ for $x = -5, 0, 3, -9$
Then sketch the graphs of $y = f(x) + 2$ and $y = f(x) - 2$.
2. **Find original $f(x)$ values at points:**
From the graph points:
- $f(-9) = 4$
- $f(-5) = -1$
- $f(0) = -9$
- $f(3) = 1$
3. **Calculate values for Table 1 ($f(x) + 2$):**
- $f(-9) + 2 = 4 + 2 = 6$
- $f(-5) + 2 = -1 + 2 = 1$
- $f(0) + 2 = -9 + 2 = -7$
- $f(3) + 2 = 1 + 2 = 3$
4. **Calculate values for Table 2 ($f(x) - 2$):**
- $f(-9) - 2 = 4 - 2 = 2$
- $f(-5) - 2 = -1 - 2 = -3$
- $f(0) - 2 = -9 - 2 = -11$
- $f(3) - 2 = 1 - 2 = -1$
5. **Describe the graph shifts:**
- The graph of $y = f(x) + 2$ is the original graph of $f(x)$ shifted **up by 2 units**.
- The graph of $y = f(x) - 2$ is the original graph of $f(x)$ shifted **down by 2 units**.
**Final answer:**
Table 1: $\begin{array}{c|c}
x & f(x) + 2 \\
\hline
-9 & 6 \\
-5 & 1 \\
0 & -7 \\
3 & 3
\end{array}$
Table 2: $\begin{array}{c|c}
x & f(x) - 2 \\
\hline
-9 & 2 \\
-5 & -3 \\
0 & -11 \\
3 & -1
\end{array}$
