(04.01 MC)

If y = 5x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

{(2, 5), (−3, −12), (−4, −18)}
{(−1, −8), (0, −3), (3, 12)}

Question 7(Multiple Choice Worth 5 points)
(4.02 MC)

Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table shows the relationship between the amount of money (y) remaining in Galvin's money box and the number of months (x):

Number of Months
(x)

Amount Remaining (dollars)
(y)

1

80

2

75

3

70

4

65

The equation shows the relationship between the amount of money, y, remaining in Henry's money box and the number of months, x:

Function 2:
y = −7x + 80

Which statement explains which function shows a greater rate of change?
Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month.
Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month.
Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month.
Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends –$7 each month.

The graph shows y as a function of x:

Graph of x against y shows 4 segments. Segment A is a horizontal line parallel to the x-axis. Segment B is a slanting straight line going down. Segment C is a slanting line going up. Segment D is a slanting straight line going down that touches the x-axis.

In which segment is the function constant?

A
B
C
D

The graph shows the distance Kim traveled from the mall in miles (y) as a function of time in seconds (x). The graph is divided into four segments labeled P, Q, R, and S, respectively.

Graph shows 4 segments. Segment P is a slanting straight line going up. Segment Q is a slanting line going up. Segment R is a horizontal straight line parallel to the x-axis. Segment S is a slanting straight line going down that touches the x-axis.

Which segment shows Kim waiting for a cab?

P
Q
R
S
