• x ≥ 5

• x < 5

• x ≤ 5

What is the range of the graph?

• (-∞,∞)

• [0,∞)

• (0,5)

• [-1,∞)

Given {x| x ≥ 6}, the domain of a function in set builder notation, which of the following rewrites it in interval notation?

What is the Domain of this linear function?

• -6 ≤ x ≤ 6

• 2 ≤ x ≤ 7

• No Solution

Write the following in interval notation
x < 3 or x ≥ 5

• (3, -∞) or (∞, 5]

• [-∞, 3) or [5, ∞]

• (-∞, 3) or [5, ∞)

• (3, -∞] or [∞, 5]

Express the following interval in Set notation:
[3, 5]
