What is the range of the following graph?

• -5, -1,  0 , 1, 5

• -4, -2, 0, 3, 6

• (-4, 1)  ( 6, 0)

• (6, 0)

All of the y values or outputs are called what?

• Domain

• Range

• Relation

• Function

Is this set of ordered pairs a function or not a function? 

• Function

• Not a Function 

Which relation is NOT a function?

• {(1,-5), (3,1), (-5,4), (4,-2)}

• {(2,7), (3,7), (4,7), (5,8)}

• {(1,-5), (-1,6), (1,5), (6,-3)}

• {(3,-2), (5,-6), (7,7), (8,8)}

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.
