Functions vs Non Functions Graphs

Does the function mapping represent a function?

• It does represent a function because each input has one output.

• It does represent a function because each output has one input.

• It does not represent a function because an input has more than one output.

• It does not represent a function because an output has more than one input.

Does the graph represent a function?

• The graph is a function because it passes the vertical line test.

• The graph is a function because it passes the horizontal line test.

• The graph is not a function because it fails the vertical line test.

• The graph is not a function because it fails the horizontal line test.

Does the function map represent a function?

• It does because each output has one input.

• It does because each input has one output.

• It does not because an input has more than one output.

• It can not be determine whether or not it is a function.

Is this graph a function or not a function? 

• Function

• Not a 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
