CCSS.8.F.A.1

State the domain of the following function:

{(-6,2), (2,5), (7,4), (-5,5), (-1,3)}

State the range of the following function:

{(-6,2), (2,5), (7,4), (-5,5), (-1,3)}

Dayne is using a pump to drain a 20,000 gallon pool. The pump drains the water at a rate of 1,000 gallons per minute. The following equation models the draining of the pool, d(x) = 20,000 - 1,000x. Identify the domain.

• [0, 20,000] gallons

• (0, 20) minutes

• [0, 20] minutes

Using the table to the left, write an equation for the function.

Is this mapping a function or not a function? 

• Function
• Not a Function

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.
