Express the following in interval notation:

-9 < x ≤ -4

• [-9, -4]

• (-9,-4]

• [-9, -4]

• (-9,-4)

What is the range in interval notation?

• (-3, 3)

• [-4, 5)

• [-4 , 5]

• (-3 , 3]

What is the domain of the graph in interval notation?

Write the following range in set-builder notation:

(4, ∞).
