Question

Write the interval (-5,9] in set builder form?

Answer 1

Given: The interval (-5,9].

To find: Write the interval (-5,9] in set builder form.

Solution:

• Now the given interval is (-5,9].

• In this ( ) means the end values are not considered.

• []  means the end values are considered.

• So let x be an element in set S.

• So:

• S = {x : x ∈ R , -5 < x ≤ 9 }

Answer:

          So the interval (-5,9] can be written as S = {x : x ∈ R , -5 < x ≤ 9 } in set builder form.
