Question

Select the appropriate notation to represent the inequality below.

x < 4
O (-∞0, 4]
O [-∞, 4]
O (-00, 4)
O (4,00)

Answer 1

The appropriate notation to represent the inequality x < 4 is O (-∞, 4)

Explanation:

This notation states that x can be any value less than 4.

The other options are:

(-∞0, 4]: This notation states that x can be any value between negative infinity and 4, including 4.

[-∞, 4]: This notation states that x can be any value between negative infinity and 4, including negative infinity and 4.

(-00, 4): This notation is not a valid notation.

(4,00): This notation states that x can be any value greater than 4.
