Consider the function:{(3,11),(4,18),(5,27),(6,38)}  What is the Domain?

• {4,11,5,18}
• {3,11,4,18}
• {3,4,5,6}
• {11,18,27,38}

Consider the function:{(3,11),(4,18),(5,27),(6,38)}  What is the Range?

• {4,11,5,18}
• {3,11,4,18}
• {3,4,5,6}
• {11,18,27,38}

For a graph of a relation to pass the vertical line test the line may only touch the graph:

• one time.
• two times.
• three times.
• not at all.

Is this graph 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
