Is this a function? Explain.

• Yes; it passes the horizontal line test.
• No; it is not a straight line.
• Yes; it passes the vertical line test.
• No; there is a line connecting the dots.

Does this mapping represent a function? Why or why not?

• Yes, this is a function because all the x values are different.
• No, this is not a function because not all the x values are different.
• Yes, this is a function because all the y values are different.
• No, this is not a function because not all the y values are different.

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.
