Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values

CCSS.8.F.A.1

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.

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}

A function is a set of ordered pairs where each x value has one y value.

Which relation is NOT a function:

• (0, 1), (2, 3), (4, 5), (6, 7)

• (0, 0), (1, 1), (2, 2), (3, 3)

• (1, 2), (1, 3), (1, 4), (1, 5)

• (1, 1), (2, 1), (3, 1), (4, 1)

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)

• -4, 4, 8, 9
• -2, 3, 8, 10
• (9, -2) ( 4, 3)
• (8, 10) (-4, 8)

How do you determine if a relation is a function? 

• The vertical line test crosses more than one point on the graph.
• The same y-values are mapped from the same x-values.
• The vertical line test crosses only one point on the graph.
• Each input is related to more than one output.
