Functions vs Non Functions Graphs

Which graph(s) show nonlinear functions?

• Graph I, only

• Graph II, only

• Graph I and Graph II, only.

• Graph I, Graph II, and Graph III

Which statement is true?

• Both Graphs have multiple y intercepts

• Both graphs are not functions

• The first graph is linear because it has a constant rate of change.

• The second graph is nonlinear but has a constant rate of change.

Which of the following relations represents a function?

• A

• B

• Both A and B

• Neither A nor B

Which is a true statement about the graph shown?

• It does not represent a function because it does not contain (0,0)

• It does not represent a function because it is a straight line.

• It represents a function because it passes the vertical line test.

• It represents a function because it crosses the x-axis only once.

Which correctly describes the graph?

• Linear and function

• Non linear and function

• Non linear and not a function

• Linear and not a function

Which graph does NOT pass the vertical line test? A vertical line should only touch one point at a time, if it is a function.

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Does the graph represent a function? Does it pass the vertical line test?

• 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 that have different outputs.

• No, because there are not enough dots to tell

• Yes because the dots are all red

Look at the graph.

Is this relation a function?

• Yes

• No

Does the 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 this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no repeating input values
