the subset of the real number consisting of all real numbers x that lie between a and b, excluding a and b, can be denoted by a<x<b or by the open interval? True or False?

Answer 1

Hi Marshmellow,

This could change if there's other information you have from previous problems, but in the question as asked, we don't know which of a or b is larger. Without that information, we can't use the greater than or less than symbols to describe the subset of real numbers x.
