The domain of a function consists of all the possible input values (usually \( x \)-values) that are valid for the function. Based on the set of points you've provided:

\[
(-3, -7),\ (8, -2),\ (0, 9),\ (-1, -7)
\]

The domain is simply the set of all the \( x \)-coordinates from the points:

\[
\{-3, 8, 0, -1\}
\]

So, the domain of this function is \( \{-3, 8, 0, -1\} \).

Would you like to explore any specific part of this? Here are some related questions:

1. What is the range of this function?
2. Can this function be considered a one-to-one function?
3. How do you determine the domain of a function from a graph?
4. What if a function has an undefined value, how does that affect its domain?
5. What is the domain for a function with an equation, rather than just points?

**Tip:** The domain includes all \( x \)-values, and the range includes all \( y \)-values.

What is the domain of this function? (-3,-7) (8,-2) (0,9) (-1,-7)

Understand how to determine the domain of a function given a set of points. This example includes the points (-3,-7), (8,-2), (0,9), and (-1,-7). Learn key concepts related to domains and functions, suitable for students in Grades 8-10.
