How do you determine if a relation is a function? 

• The vertical line test crosses more than one point on the graph.

• The same y-values are mapped from the same x-values.

• The vertical line test crosses only one point on the graph.

• Each input is related to more than one output.

Three relations are shown in the image. Which of these relations is a function?

• A only

• A, B and C

• A and B only

• B only

• B and C only
