Unit 1 Final Review

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c=34.95u+6.25, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation?

A student is taking a test that has 10 questions on it. The student's score is a function of how many questions he misses: f(x)=100-10x, where x is the number of questions incorrect. What is the range?

• 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

• 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

• 0 < y < 100

• y < 100

James is creating a budget. He has exactly $20.25 to spend on gas each month. Gas is currently $2.25 a gallon. If the function f(x)=20-2.25x represents the amount of money he has left after buying x gallons of gas, what is the domain?

• 0 < x < 9

• 0 < y < 9

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

• 0 < x

If I join the gym for a start up fee of $40 and monthly fee of $10, what is the range? (Equation: f(x)=40+10x)

• -4, -3, -2, -1, 0.....

• $10, $20, $30, $40......

• 0, 1, 2, 3.....

• $40, $50, $60.....

A home security company provides security systems for $5 per week, plus an installation fee. The total fee for 12 weeks of service is $210. Write a linear equation to find the cost of the installation fee.

• y = 5x + 12

• y = 5x + 150

• y = 12x + 210

• y = 12x + 5

The value of a car decreases at a constant rate. After 3 years, the value of the car is $15, 000. After 2 more years, the value of the car is $11,000. Write a linear equation to find value of the car.

• y = 3x + 21000

• y = 3x + 15000

• y = -2000x + 21000

• y = 2000x + 21000
