Identifying Function from Ordered Pairs, Table or Mapping Diagram

The following ordered pairs represent a relation.
{(1,3) , (5,15) , (2,6), (4,12) , (3,9)}
What are the range values from least to greatest!

• {1, 5, 2, 4, 3}

• {3, 15, 6, 12, 9}

• {3}

• {3, 6, 9, 12, 15}

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

• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

Is this relation a Function?

• Yes

• No

• I Don't Know

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• 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.

Does this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no repeating input values

• Function
• Not a Function

How can you tell if a graph is a linear function based on its points?

• The points form a straight line with a constant slope.

• The points form a circle with varying radii.

• The points are randomly scattered without any pattern.

• The points create a parabolic curve.

Which set of ordered pairs is a function?

• <(9,5), (10,5), (9,-5), (10,-5)>

• <(3,4), (4,-3), (7,4), (3, 8)>

• <(6,-5), (7, -3), (8, -1), (9, 1)>

• <(2, -2), (5, 9), (5, -7), (1, 4)>

Which of these tables represent a function?

• A

• B

• C

• D
