The LNHS Lions stadium seats about 2,000 people. The tickets sell for $6 each. The function f(x) = 6x represents the situation where x is the number of people in attendance and f(x) is the amount of money LNHS makes as revenue.

What is the domain of the situation?

• x is all real numbers

• 0 < x < 2,000

• 0 < x < 6 where x is all non-negative integers

• X is the set of all whole numbers < 2,000

What is the range of the situation?

• 0 < f(x) < 6

• 0 < f(x) < 2,000

• 0 < f(x) < 12,000

• 2,000 < f(x) < 12,000

A downtown shop rents scooters for a one-time cost of $20.50 plus $7.50 per hour. Which equation can be used to find y, the total cost that a group of people must pay to rent x scooters for 8 hours?

• y = 28 + 8x

• y = 20.50 + 60x

• y = 224x

• y = 80.50x

The table represents some points on the graph of a linear function. Which function represents the same relationship shown in the table?

• f(x) = -3x – 10.5

• f(x) = x – 3.5

• f(x) = 3x – 10.5

• f(x) = -x – 3.5
