STAAR Review DAY 2: 2A & 12B IP

A mechanical bull ride game can be rented out for parties at a cost of $95 per hour. The ride can be

rented for either 1, 2 or 3 hours. The cost in dollars to rent the ride is a function of the number of hours

the ride is rented.

What are the domain and the range of the function for this situation?

• a. Domain: {1,2,3} Range: {95,190,285}

• b. Domain: {95,190,285} Range: {110, 220}

• c. Domain: all real numbers Range: all real numbers

• d. Domain: x ≥ 0 Range: y ≥ 0
