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

3 answers

x is greater than 9 but less than 14?
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]?
So would this be Parentases? Because the 9 and 14 are not included as the solution?
