Domain, Range, Is a Relation a Function

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

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

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}

• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}

• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}

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

• {1, 2, 3, 4, 5}
• {-1, 1, 2, 3}
• {1, 2, 3, 5}
• [1, 5]

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

Does the table represent a function or not a function?

• Function

• Not a Function

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.
