Notation Practice

Express the following in Interval Notation

-8 ≤ x < 8

• [-8, 8]

• [-8,8)

• (-8, 8]

• (-8, 8)

Express the following interval in Set notation:

[3, 5]

• {x | 3 ≤ x ≤ 5}

• {x | 3 < x ≤ 5}

• {x | 3 ≤ x < 5}

• {x | 3 < x < 5}

Write the following in interval notation
 x < 8

• (8, ∞)
• (8, -∞)
• (-∞, 8)
• [-∞, 8]
