write interval notation for the set {x|-7<x<7} choose a intervel

A)[-7,7)
B)(-7,7)
C)(-7,7]
D)[-7,7]

The correct interval notation for the set {x|-7<x<7} is:

B) (-7, 7)

To convert the set {x|-7<x<7} into interval notation, you need to consider the type of inequality used in the set.

In this case, the symbol "<" is used, which means the endpoints -7 and 7 are not included in the interval.

The correct interval notation for this set is option B)(-7,7).

the answer is B. The parentheses represent that it is not inclusive. So since its -7<x<7 (not inclusive on both sides) then you use parentheses on both sides. If it were -7<=x<=7 then it would be D. hopefully that makes sense? :)
