Identifying Functions from Graph

Which graph represents a function?

• 
• 
• 
• 

• Function

• Not Function

Consider the graph of a relation. If a vertical line intersects the graph at more than one point, is the relation a function?

• Yes, it is a function

• No, it is not a function

• It depends on the type of graph

• Cannot be determined

If a graph passes the vertical line test, what can be concluded about the graph?

• It is a function

• It is not a function

• It is a linear function

• It is a quadratic function

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
