1. **Problem Statement:**
We are given a function $f(x)$ with inputs and outputs in a table and asked to complete the table for its inverse function $f^{-1}(x)$.
2. **Understanding the inverse function:**
The inverse function $f^{-1}(x)$ reverses the roles of inputs and outputs of $f(x)$. That means if $f(a) = b$, then $f^{-1}(b) = a$.
3. **Given table:**
$$\begin{array}{c|cccccc}
x & -7 & 11 & -13 & 6 & 5 & -9 \\
f(x) & 7 & 12 & 8 & -7 & 13 & 5 \\\end{array}$$
4. **Complete the inverse table:**
Swap the rows and columns for $f^{-1}(x)$:
- Since $f(-7) = 7$, then $f^{-1}(7) = -7$
- Since $f(11) = 12$, then $f^{-1}(12) = 11$
- Since $f(-13) = 8$, then $f^{-1}(8) = -13$
- Since $f(6) = -7$, then $f^{-1}(-7) = 6$
- Since $f(5) = 13$, then $f^{-1}(13) = 5$
- Since $f(-9) = 5$, then $f^{-1}(5) = -9$
So the inverse table is:
$$\begin{array}{c|cccccc}
x & 7 & 12 & 8 & -7 & 13 & 5 \\
f^{-1}(x) & -7 & 11 & -13 & 6 & 5 & -9 \\\end{array}$$
5. **Find the requested values:**
- $f^{-1}(f^{-1}(13))$:
- First, $f^{-1}(13) = 5$
- Then, $f^{-1}(5) = -9$
- So, $f^{-1}(f^{-1}(13)) = -9$
- $f^{-1}(8)$:
- From the table, $f^{-1}(8) = -13$
- $f^{-1}(f(10))$:
- We need $f(10)$, but $10$ is not in the domain table, so we cannot find $f(10)$ from the given data.
- Since $f(10)$ is unknown, $f^{-1}(f(10))$ cannot be determined from the given information.
6. **Matching function with inverse type:**
- The function $f(x) = 3x - 5$ is a linear function, not quadratic.
- Its inverse is also linear, given by solving $y = 3x - 5$ for $x$:
$$x = \frac{y + 5}{3}$$
**Final answers:**
- Completed inverse table:
$$\begin{array}{c|cccccc}
x & 7 & 12 & 8 & -7 & 13 & 5 \\
f^{-1}(x) & -7 & 11 & -13 & 6 & 5 & -9 \\\end{array}$$
- $f^{-1}(f^{-1}(13)) = -9$
- $f^{-1}(8) = -13$
- $f^{-1}(f(10))$ cannot be determined from the given data.
- $f(x) = 3x - 5$ is a linear function, so its inverse is linear, not quadratic.
