We are given:

• Set $A = \{-2, -1, 0, 1, 2\}$
• Set $B = \{0, 1, h, 9\}$
• Relation $R = \{(2,4), (-1,1), (0,0), (1), (2.4)3\}$

There seems to be some confusion with the formatting of relation $R$. I'll assume it's intended to be:

$R = \{(2, 4), (-1, 1), (0, 0)\}$

Let’s now proceed with the calculations:

1. Domain of $R$:

The domain of $R$ is the set of all the first elements of the ordered pairs in $R$.

So, the domain of $R$ is: $\text{Dom}(R) = \{2, -1, 0\}$

2. Range of $R$:

The range of $R$ is the set of all the second elements of the ordered pairs in $R$.

So, the range of $R$ is: $\text{Range}(R) = \{4, 1, 0\}$

3. $6 - \text{Dom}(R)$:

Now, to compute $6 - \text{Dom}(R)$, we subtract each element of the domain from 6: $6 - \text{Dom}(R) = \{6 - 2, 6 - (-1), 6 - 0\} = \{4, 7, 6\}$

Summary:

• Domain: $\{2, -1, 0\}$
• Range: $\{4, 1, 0\}$
• $6 - \text{Dom}(R) = \{4, 7, 6\}$

Let me know if you'd like further details or explanations.

Here are five related questions you can explore:

1. What is the domain and range of the relation $R = \{(-2, 3), (1, -4), (0, 5)\}$?
2. How do you determine if a relation is a function?
3. Can the domain of a relation contain repeated values?
4. How do you represent a relation using a matrix?
5. How do you find the inverse of a relation?

Tip: Always ensure that relations are written clearly to avoid confusion with their elements and structure.
