• Yes, because the x never repeats.

• Yes, because they are individual dots.

• No, because the x repeats.

• No, because it is not a line.

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Which statement about the relation is true?

• The relation is not function because is not continuous.

• The relation is a function because the x-values of the points are consecutives integers.

• The relation is a function because there is only one output for each input.

• The relation is not a function because both 0 and -3 are outputs for the input 1
