True or False:
4 is a domain value in the function graphed.

• True

• False

• -5 ≤ x ≤ -1
• -4 ≤ y ≤ 4
• { -4, 0, 2, 4 }
• { -5, -4, -3, -1 }

Identify the domain of the following relation:

• {-6, 14, 2, 28}

• {(-6,14), (0,32), (2,38), (4,44)}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

Is this mapping 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.

Which set of values 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)
