In the set of ordered pairs {(-2,0), (0,6), (2,12), (4,18)}, what is the domain?

• {-2, 6, 2, 4}

• {0, 0, 2, 4}

Does the table represent 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 graph IS a function?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Which graph is NOT a function?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Athar is buying hats for his baseball team. The shipping charge is $5. and each hat costs $8. There are ten people on his baseball team. The graph shows the total cost of the hats. SELECT ALL TRUE STATEMENTS

• The ordered pair for 1 hat bought is (1, 8)

• The domain is whole numbers of hats from 1 - 10

• The range is dollars from 0 - 100 in increments of 5

• The ordered pair for 5 hats bought is (5, 45)

• The cost of ordering 10 hats is double the cost of ordering 5 hats

If the DOMAIN of the function

y = 4x + 1

is all the values between 0 and 10,

what is the RANGE of the function?

• None of these

• 0 - 40

• 0 - 10

• 1 - 41
