2. Which of the graphs show continuous functions? Select two answers.
A.
A graph is shown in the xy-plane. The values on the x-axis ranges from negative 6 to 6 in increments of 2 and the values on the y-axis ranges from negative 8 to 8 in increments of 2. A line starts from a point in the second quadrant, goes down, passes through the points (negative 6, 4), (negative 2, 2), (0, 1), (2, 0), and so on.
B.
A graph is shown in the xy-plane. The values on the x-axis ranges from negative 6 to 6 in increments of 2 and the values on the y-axis ranges from negative 8 to 8 in increments of 2. Five points are marked on the graph whose coordinates are (negative 2, 7), (negative 1, 4), (0, 2), (1, 4), and (2, 7) respectively.
C.
A graph is shown in the xy-plane. The values on the x-axis ranges from negative 3 to 3 in increments of 1 and the values on the y-axis ranges from negative 8 to 8 in increments of 2. Five points are marked on the graph whose coordinates are (negative 2, 9), (negative 1, 2), (0, 1), (1, 0), and (2, negative 7) respectively.
D.
A graph is shown in the xy-plane. The values on the x-axis ranges from negative 3 to 3 in increments of 1 and the values on the y-axis ranges from negative 8 to 8 in increments of 2. A non-uniform curve is shown which starts from a point in the second quadrant, goes down, passes through the points (negative 1 decimal point 5, 6), (negative 1, 2), (0, 0), then enters the fourth quadrant. Then goes up, intersects the x-axis at 1, enters the first quadrant, and passes through (1 decimal point 5, 4), and ends in the first quadrant.

A graph is shown in the xy-plane. The values on the x-axis ranges from 0 to 7 in increments of 1 and the values on the y-axis ranges from 0 to 80 in increments of 10. A line starts from a point 25 on the y-axis, goes up and passes through the points (1, 35), (2, 45), and so on.
A.
$10.00
B.
$20.00
C.
$25.00
D.
$45.00
