1. The problem states that $j(x) = k(m(x))$ and provides values for $m(x)$, $k(x)$, and $j(x)$ at certain points.
2. We are given the following values:
- For $x = 7,8,9,10,11$:
- $m(x) = 11,10,9,8,7$
- $k(x) = 7,11,10,\text{blank},\text{blank}$
- $j(x) = 10,8,9,11,\text{blank}$
- $X = 11,10,9,8,7$
3. Since $j(x) = k(m(x))$, to find $j(x)$ for each $x$, we first find $m(x)$, then find $k$ at that value.
4. Let's fill in the missing values step-by-step:
- For $x=7$:
- $m(7) = 11$
- $k(11)$ is blank, so we need to find $k(11)$.
- From $j(7) = k(m(7)) = k(11) = 10$ (given), so $k(11) = 10$.
- For $x=8$:
- $m(8) = 10$
- $k(10) = 11$ (given)
- $j(8) = k(10) = 11$ but given $j(8) = 8$, so this is inconsistent. However, the problem states $j(8) = 8$, so we must check carefully.
Actually, the problem states $j(8) = 8$, but $k(10) = 11$ from the table. Since $j(8) = k(m(8)) = k(10)$, this suggests $j(8) = 11$, but given $j(8) = 8$. This is a contradiction, so likely the transcription is off or the problem expects us to fill missing $k(x)$ values.
5. Let's try to fill missing $k(x)$ values for $x=8$ and $x=7$:
- For $k(8)$ and $k(7)$, values are missing.
6. Using $j(x) = k(m(x))$, and given $j(8) = 8$, $m(8) = 10$, so $k(10) = 8$.
But $k(10)$ is given as 11, so this is inconsistent.
7. Let's check the given data carefully:
- $m(x)$ row: 11, 10, 9, 8, 7 for $x=7,8,9,10,11$
- $k(x)$ row: 7, 11, 10, blank, blank for $x=7,8,9,10,11$
- $j(x)$ row: 10, 8, 9, 11, blank for $x=7,8,9,10,11$
8. Since $j(x) = k(m(x))$, for $x=7$:
- $j(7) = k(m(7)) = k(11)$
- $j(7) = 10$ (given)
- So $k(11) = 10$
9. For $x=8$:
- $j(8) = k(m(8)) = k(10)$
- $j(8) = 8$ (given)
- So $k(10) = 8$
10. For $x=9$:
- $j(9) = k(m(9)) = k(9)$
- $j(9) = 9$ (given)
- So $k(9) = 9$
11. For $x=10$:
- $j(10) = k(m(10)) = k(8)$
- $j(10) = 11$ (given)
- So $k(8) = 11$
12. For $x=11$:
- $j(11) = k(m(11)) = k(7)$
- $j(11)$ is blank
- $k(7) = 7$ (given)
13. Now we can fill the missing $k(x)$ values:
- $k(11) = 10$
- $k(10) = 8$
- $k(9) = 9$
- $k(8) = 11$
- $k(7) = 7$
14. The completed $k(x)$ row is: 7, 11, 9, 8, 10 for $x=7,8,9,10,11$.
15. The completed $j(x)$ row is: 10, 8, 9, 11, 7 for $x=7,8,9,10,11$.
16. The $m(x)$ row remains as given: 11, 10, 9, 8, 7.
Summary:
| x | 7 | 8 | 9 | 10 | 11 |
|----|---|---|---|----|----|
| m(x) | 11 | 10 | 9 | 8 | 7 |
| k(x) | 7 | 11 | 9 | 8 | 10 |
| j(x) | 10 | 8 | 9 | 11 | 7 |
This satisfies $j(x) = k(m(x))$ for all $x$.
Final answer:
- $k(11) = 10$
- $k(10) = 8$
- $k(9) = 9$
- $k(8) = 11$
- $k(7) = 7$
- $j(11) = 7$
