Chapter 3 Quiz

Is Y a function of X?

• yes, passes the vertical line test

• yes, passes the horizontal line test

• no, fails the vertical line test

• no, fails the horizontal line test

Is this mapping a function or not a function? 

• Function
• Not a Function

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Is this set of ordered pairs a function and how can you tell?

• Yes its a function because no y values repeat
• No it's not a function because there are negative numbers
• No it isn't a function because an x value repeats but has different y values 
• No it isn't a function because an y value repeats but has different x values
