CCSS.8.F.A.1

State the domain of the following function:

{(-7,2), (3,5), (8,4), (-6,5), (-2,3)}

State the range of the following function:

{(-7,2), (3,5), (8,4), (-6,5), (-2,3)}

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.
