Interval Notation for Domain and Range

What is the domain of the function?

• (3, ∞)

• [-3, ∞)

• (-∞, 4]

• (-∞, 4)

What is the range?

• [-7,6]

• (-7,6)

• (-8, 2)

• [-8,2]

What is the range?

• (-3, 3)

• [-4, 5)

• [-4 , 5]

• (-3 , 3]

What is the domain in Interval notation?

Hint: Notice that there are NO ARROWS!

The function is a line-segment. It ends on both sides.

• [ -2 , 2 ]

• [ 4 , -4 ]

• -2 ≤ x ≤ 2

• 4 ≥ y ≥ -4

What is the domain of the graph?

• [ -∞, ∞]

• (-∞,∞)

• [-3 , 3]

• [-15, 9]

What is the range of the graph?

• -15 < y < ∞

• (-∞, ∞)

• (-15, ∞)

• [-15, ∞)

Which graphs have a range of (-∞, 3]
