Express the solution set x>3 in interval notation

The solution set \( x > 3 \) in interval notation is expressed as:

\[
(3, \infty)
\]

This means that \( x \) can take any value greater than 3, but not including 3 itself.

Would you like more details on this process or have any questions?

Here are 5 related questions to expand your understanding:
1. How would you express \( x \geq 3 \) in interval notation?
2. How would you express \( x < 3 \) in interval notation?
3. What is the interval notation for \( x \leq 5 \)?
4. Can you express the inequality \( 2 < x \leq 7 \) in interval notation?
5. How do we express all real numbers in interval notation?

**Tip:** When using interval notation, round brackets \( () \) indicate that an endpoint is excluded, while square brackets \( [] \) indicate that an endpoint is included.
