solve the equivalent interval notation of x < -4

The inequality \( x < -4 \) represents all values of \( x \) that are less than -4. In interval notation, this is written as:

\[
(-\infty, -4)
\]

This means that \( x \) can take any value from negative infinity up to, but not including, -4.

Would you like further details on interval notation or have any questions?

Here are 5 related questions:
1. How would you express \( x \leq -4 \) in interval notation?
2. What is the interval notation for \( x > 5 \)?
3. Can you express \( -2 \leq x < 3 \) using interval notation?
4. How do you combine intervals for inequalities like \( x < -4 \) or \( x > 2 \)?
5. What is the interval notation for \( -1 < x \leq 4 \)?

**Tip:** Always remember that round brackets \( () \) indicate that an endpoint is not included, and square brackets \( [] \) indicate that it is included.
