Work Step by Step
The first bracket represents the settings for the x-axis while the second represents the settings for the y-axis. For each bracket, the first two numbers represent the starting and ending coordinates. The third represents the distance between ticks. Thus, the given viewing rectangle means: (i) The x-values vary from -40 to 40. The distance between ticks is equal to 20 units. This means that there are 2 ticks to the left of 0 and 2 ticks to the right. (ii) The y-values vary from -1000 to 1000. The distance between ticks is equal to 100 units. This means that there are 10 ticks above 0 and 10 ticks below. The graph that meet these settings is the one in Option (a).
