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.

• 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.

Answer 2

{x : x is element of R, -5 < x < 9 }
