Kira wanted to study how the area of a rectangle changes with the length of its width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then plotted the results and connected them with a line, as shown above. The graph shows the area (in cm ^2) versus the length (in cm). Find the range and the domain of the function shown in the picture above.

Write your answers as inequalities, using x or y as appropriate. Or, you may instead clock on “empty set” or “all reals” as the answer.

A. Range: _

B. Domain: _
