Question

Jessica wanted to study how the area of a rectangle changes with the length if 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 below. The graph shows the area (in m) versus the length (in m) Find the range and the domain of the function shown.​

Answer 1

Domain:
`(2,0)`

Range:
`(0, all\:real \: numbers)`

Explanation:

The domain is the x-axis. So it is pointed at 2 and there is no other half of the graph, so it is zero. The line goes up. Therefore, it passes the graph, making it any number for the range.
