• (-2, 4)

• (4, 4)

Is this a function or not?

• Function

• Not a Function

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers

• Yes its a function because there are repeated x values

• No it isn't a function because the x value 1 is repeated

• No it's not a function because the x value 2 and 5 are repeated.

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

What is the definition of the domain of a function?

• the set of all x-values or inputs

• the set of all y-values or outputs

• The function itself

What is the definition of the range of a function?

• The set of all y values or outputs

• The set of all x values or inputs

• The function itself

What is the domain?
