(03.02 MC) The table below shows the squares of different numbers:

Number (x)	2	−2	3	−3
Square of the number (y)	4	4	9	9

Part A: Does the table represent y as a function of x? Justify your answer. (5 points)
Part B: The total cost f(x), in dollars, for renting a rowboat for x hours is shown below:
f(x) = 20 + 3x
What is the value of f(150), and what does f(150) represent? (5 points)
(10 points)

Part A: Yes it does because y is dependent on x.

Part B: $470.

(03.06 MC) Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 54 km/h. After four hours, the velocity of the car is 58 km/h.
Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5 points)
Part B: How can you graph the equation obtained in Part A for the first six hours? (5 points)
(10 points)

Part A: x=starting point for the measurement.  y=the amount of hours measured.  v-final velocity.  x + 1y = v

Part B: If x is 54 km/h then 54 + 6 + 60.

(05.06 HC) The coordinate plane below represents a city. Points A through F are schools in the city.

Part A: Using the graph above, create a system of inequalities that only contain points D and E in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)
Part B: Explain how to verify that the points D and E are solutions to the system of inequalities created in Part A. (3 points)
Part C: Timothy can only attend a school in his designated zone. Timothy's zone is defined by y < 3x − 3. Explain how you can identify the schools that Timothy is allowed to attend. (2 points)
(10 points)

Part A: y < x and y > -2x

Part B: Point B verifies it.

Part C: y > 1/2x
