What is the DOMAIN of the graph?

• 
  

  $\left[-3,3\right]$

• $\left[3,-3\right]$

• $\left[-2,10\right]$

• $\left(-2,10\right)$

What is the DOMAIN of the graph?

• $\left(-\infty,\infty\right)$

• $\left[0,\infty\right)$

• $\left(-\infty,0\right)$

• $\left[-3,3\right]$
  

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.
