What is the domain of the graph?

What is the domain of a relation?

• the set of all x-values

• the set of all y-values

Is this table a function and how can you tell?

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

• No it's not a function because the y value 4 repeated

• No it isn't a function because the x value 2 has the same y

• No it's not a function because the x value 5 has 2 outputs.

Is this graph a function? (Vertical Line test)
