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.

What is the domain of this function?
{(0,2), (3,5), (5,8), (7, 11)}

• {2,5,8,11}
• {0,3,5,7}
• [0,7]
• [2,11]

CCSS.HSF.IF.B.5

Is this a function?  Why or why not? 

• Yes, because none of the domain numbers repeated.
• Yes, because none of the range letters repeated.
• No, because 3 goes to A and 4 goes to A.
• No, because A gets used twice.

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function! 

• 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
