Which interval notation represents the set of all numbers greater than or equal to 5 and less than 12?(1) [5, 12) (2) (5, 12] (3) (5, 12)(4) [5, 12]

Interval notation is a method of writing down a set of
numbers. Consider a variable x and two numbers A and
B.

• (A, B) is used to denote
  A<x<B


• [A, B) is used to denote
  A<=x<B


• [A, B] is used to denote
  A<=x<=B


• (A, B] is used to denote
  A<x<=B

Using the rules listed
above the interval notation that represents the set of all numbers greater than or equal
to 5 and less than 12 is option 1.

The
correct interval notation is [5, 12) which is option
1.
