The total cost of registration is a function of the number of club members who register for the competition. What is the independent quantity? C:D: The range of the function The output of the function

A The number of math clubs registering

A:B: YES because there no repeating x values #8 Is the following relation a function? Why? { (-1,0), (0,-3), (2, -3), (3,0), (4,5)} C:D: 55 No because there are repeating y values No because there are repeating x values YES because there no repeating y values

B YES because there no repeating x values

A:B: #9 Is the relation a function? why? C:D: Yes, because there are no repeating inputs No, because there are repeating inputs No, because there are no repeating outputs Yes, because there are repeating outputs

C Yes, because there are no repeating inputs

A:B: {1,2,3,4,5} #10 Chris is renting roller blades for $12 a day. The rule for this situation is c = 12t, where c is the cost in dollars and t the number of days rented. What is the range if the most he rents Is for 5 days? C:D: {12,24,36, 48, 60} {-1,-2,-3,-4,-5} {-12,-24,-36, -48, -60}

D {12,24,36, 48, 60}

A:B: [0,10] #11 Chris is renting roller blades for $12 a day. The rule for this situation is c = 12t, where c is the cost in dollars and t the number of days rented. What is a reasonable domain? C:D: [-10,0] [0,  ) (- , 0]

B [0,10]

A:B: 6n + 406n - 40 #12 Andrea paints houses during her summer vacations. This year, she charged $6.00 per hour to paint plus $40 for supplies. State the rule to determine how much she earns if she paints n hours. C:D: 40n n - 6
