Question

The set {x:x∈R,-3<x<9} can be written as *

(9,-3)

(-3,9]

(-3,9)

[-3,9]​

Answer 1

Answer:

(-3,9)

The set {x:x∈R,-3<x<9} can be written as

(-3,9)

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The set { x : x ∈ R , - 3 < x < 9 } can be written as

• (9,-3)

• (-3,9]

• (-3,9)

• [-3,9]

EVALUATION

Here the given set is

{ x : x ∈ R , - 3 < x < 9 }

Now the above set represents all real numbers which is greater than - 3 and less than 9

Also in the interval ( - 3,9) which we call as open interval contains all real numbers which is greater than - 3 and less than 9

Hence the correct option is ( - 3,9)
