Question

What kind of interval notion do you get for this 9<x<14?

Answer 1

x is greater than 9 but less than 14?

Answer 2

Interval "notation" means writing a min and max value, enclosed in brackets or parentheses.

In this case (9,14)

Why parens here, not brackets? Which inequality corresponds to [9,14]?

Answer 3

So would this be Parentases? Because the 9 and 14 are not included as the solution?

Answer 4

[AI-generated answer — Explain Bot]

The interval notion for the inequality 9 < x < 14 is called an open interval. In an open interval, the endpoints are not included in the interval itself. In this case, the numbers 9 and 14 are not included in the interval, so the notation would be (9, 14). The round brackets indicate that the endpoint values are excluded from the interval.
