Oakland Coliseum, home of the Oakland Raiders, is capable of seating 63,026 fans. For each game, the amount of money that the Raiders' organization brings in as revenue is a function of the number of people, in attendance. If each ticket costs $30.00, find the domain of this function.

• 0 ≤ n ≤ 63,026 where n is all integers.

• 0 ≤ n ≤ 50,000 where n is all integers.

• 1,000 ≤ n ≤ 63,026 where n is all integers.

• 0 ≤ n ≤ 70,000 where n is all integers.

Oakland Coliseum, home of the Oakland Raiders, is capable of seating 63,026 fans. For each game, the amount of money that the Raiders' organization brings in as revenue is a function of the number of people, in attendance. If each ticket costs $30.00, find the range of this function.

• 0 ≤ f(n) ≤ 1,890,780 where f(n) is an integer multiple of 30.

• 0 ≤ f(n) ≤ 2,000,000 where f(n) is an integer multiple of 30.

• 0 ≤ f(n) ≤ 1,500,000 where f(n) is an integer multiple of 30.

• 0 ≤ f(n) ≤ 1,000,000 where f(n) is an integer multiple of 30.

The height of water in a bathtub, P(t), is a function of time, t. Let represent this function. Height is measured in inches and time in minutes. Match each statement in function notation with a description.

• P(0) = 0

• After 20 minutes, the bathtub is empty.

• P(4) = 10

• The bathtub starts out with no water.

• P(10) = 4

• After 10 minutes, the height of the water is 4 inches.

• P(20) = 0

• The height of the water is 10 inches after 4 minutes.
