what is the domain of {(-2, 5) , (4, 9) , (1, -4), (0, 5), (2, -7)}

The domain of a set of points refers to the collection of all possible input values (x-values) from each point. 

Given the set of points \(\{(-2, 5), (4, 9), (1, -4), (0, 5), (2, -7)\}\), the domain consists of all the x-values:

\[
\{-2, 4, 1, 0, 2\}
\]

This is the domain of the relation.

Here are 5 related questions for further exploration:
1. What is the range of this set of points?
2. How do you determine the domain of a function from its equation?
3. Can a domain include repeated x-values in a function?
4. What is the difference between domain and range?
5. How do you find the domain of more complex functions like square roots or rational functions?

**Tip:** For a function to be valid, each x-value (input) should have exactly one y-value (output). Repeated x-values can imply the relation is not a function!
