• Function

• Not a Function

Is this table a function or not a function? 

• Function

• Not a Function 

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.

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3}

  R:{0, 1, 2, 3, 4}
