Will mark is the interval notation for the compound inequality?

x≤3 or x> 7

(−∞, 3) or [7, ∞)

(−∞, 3] or (7, ∞)

(3,7]

[3,7)

The correct option is 2.

Step-by-step explanation:

The given inequality compound inequality is

               ... (1)

                .... (2)

From inequality (1) it is clear that value of x must be less than or equal to 3. Since 3 is included in the solution set, therefore we have a closed interval at 3.

The interval notion for inequality (1) is (−∞, 3].

From inequality (2) it is clear that value of x must be greater that 7. Since 7 is not included in the solution set, therefore we have open interval at 7.

The interval notion for inequality (2) is (7, ∞).

The interval notation for the compound inequality is

(−∞, 3] or (7, ∞)

Therefore the correct option is 2.
