Domain (range) of functions

State the domain:

• (7, oo)

  >7 to infinity

• x = -5

• x = 5

• x  = 2

• x = 2, x = -5

• x = 2, x = -5

In your own words, how would you describe the domain of a function?

What is the Domain?

• -3 ≤ x < 5
• -3 ≤ y < 5
• -8 ≤ x < 5
• -8 ≤ y < 5

What is the Range

• y ≤ 6

• y > 6

• x ≤ 6

• All Real Numbers

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

What is the domain of this function?

• 3 ≤ x <∞

• 3 ≤ x ≤ ∞
