• y = 2 + 1/2x
• y = 2 - 1/2x
• y = 1 - 2x

What is the range of the mapping shown?

A student bought concert tickets online. The total cost, c, in dollars, of t tickets can be found using the function c = $24.50t + 9.50. If the student spent a total of $230 on tickets, how many tickets did he buy?

• 9 tickets
• 5644 tickets
• 24 tickets
• 9.50 tickets

• x > 0.64
• no solution
• All Real Numbers

What is the x-intercept of the graph shown?

• (-1.5, 0)
• (0, -1.5)
• (3, 0)
• (0, 3)

What is the domain of graph shown?

1.  A city employee paints curbs in parking lots and replaces a road sign. The function below can be used to find c, the number of parking lot curbs the employee paints when he replaces r road signs in a 40 hour work week. If the employee painted 55 curbs in one week, how many road signs did he replace that week?

• 1
• 3
• 5
• 7

Does the table represent a function?

• yes, because the y-values repeat
• Yes, because the x-values don't repeat
• No, because the y-values repeat
• No, because the x-values don't repea

What is the zero of the graph shown?

• (-6, 0)
• (0, -6)
• (9, 0)
• (0, 9)

The student council sent members on four field trips during the school year.  The number of buses needed to transport the members on each trip is a function of the number of members who went on each trip. This function consists of only the ordered pairs (52, 3), (72, 4) (86, 5) and (105, 6). What is the range for this situation?

• {52, 72, 86, 105}
• 52 ≤ x ≤ 105
• {3, 4, 5, 6}
• 3 ≤ y ≤ 6
