Does the graph represent 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

Is this a function? 

• Yes 
• No

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D:{0, 1, 2, -4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3}
  R:{0, 1, 2, 3, 4}
