The image contains a mathematical expression which appears to include set notation. From what I can interpret, the expression looks like:

\[
x \in \mathbb{R} \setminus \{-1, 1, 3\} = ?
\]

This can be understood as: "What is \( x \) belonging to the set of real numbers \( \mathbb{R} \), but excluding the values \(-1\), \(1\), and \(3\)?"

This kind of expression defines a domain of \( x \), specifically excluding certain values from the real number set.

Would you like more details about the meaning of this set notation or its application? Let me know if you'd like a further breakdown!

Here are some related questions for further exploration:
1. How do you define a set in mathematics?
2. What are real numbers, and how are they represented?
3. What is the significance of excluding certain values in set notation?
4. How does set difference \( A \setminus B \) work in mathematics?
5. How does set notation help in defining domains in functions?

**Tip**: Set notation is commonly used in calculus and algebra to define domains and ranges where certain operations or functions are valid.
