Jillian plays a game that involves stacking blocks in a tower. The graph
shows the height of the tower based on the number of blocks she uses.
Height (mm)
-200
100
What is the range of the graph?
Number of blocks
510
OA. {0, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200}
B. {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
C. All integers
D. 0 ≤ y ≤ 200

The range of a function is defined by its minimum and maximum values of y or the vertical axis. We are looking for which y-values are present in the function, denoted by the placement of each value's height on the graph. As the function is not linear, it does not have a continuous range and cannot be D. This discrete function starts with a minimum range of 0 (from the y-value 0 in (0, 0)) and a maximum range of 200 (from the y-value in (10, 200)). As no other sets end with the maximum value in the range 200, we can assume that it is answer A. To be sure, we can determine the entire set of the range by retrieving the y-values of each coordinate of the function and ensuring that it has the same values as option A.
