Write the set {x|x<-1} in interval notation.
What does it mean INTERVAL NOTATION?

Can be intervals from a number less than -1 and infinity.....that is only possible if a limit to the value approching -1...is this the complete question? cox if it was x<=-1 than the intervals would be (-�‡,-1)
translate to an algebraic expression 46 divided by d
Interval notation is a way to represent a set of real numbers using intervals.
In interval notation, we use brackets and parentheses to describe the boundaries of the set. Here's how the notation works:
- Square brackets [ ] are used to include the endpoints.
- Round brackets ( ) are used to exclude the endpoints.
Now, let's apply this notation to the set {x | x < -1}.
The set {x | x < -1} represents all real numbers "x" such that "x" is less than -1. To express this set in interval notation, we should first determine which type of bracket to use at each boundary.
Since the inequality is strict (x < -1), the endpoints are not included in the set. Therefore, we use round brackets to represent that they are excluded.
- The left boundary has no specified lower limit, so we use negative infinity as the left endpoint.
- The right boundary is -1, but it is excluded, so we use round brackets around it.
Putting it all together, the set {x | x < -1} in interval notation is (-∞, -1).
