• No, each input has more than one output

• No, the cost of the movies is different

• Yes, each output has one input

List the ordered pairs

• Input and Output

• (-1, 1), (-2, 1), (-3,2), (-4,2)

• (1,1) (2,4)

• (1,-1), (1,-2), (2,-3), (2,-4)

Describe the pattern input and output

• The input and output both go down by 3

• The x goes up 1 and the y goes right 1

• The x goes right 2 and the y goes up 2

• There is no pattern

Describe the pattern of inputs and outputs

• The x and y move by 1

• The x moves right by 2 and the y stays the same

• The x does not move and the y does not move

• The x moves down by 1 and y moves up

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 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.
