Question

Jina wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then employed the results and connected them with a line, as shown in the picture. The graph shows the area (in m2) versus the length (in m)

Find the range and domain for the functions shown.
(A). Domain:
(B). Range:
​

Answer 1

Explanation:

Answer 2

The domain and the range of the function are, respectively:

`Dom\{f\} = [0\,m,5\,m]`

`Ran\{f\} = [0\,m^(2), 10\,m^(2)]`

Explanation:

Jina represented a function by a graphic approach, where the length, measured in meters, is the domain of the function, whereas the area, measured in square meters, is its range.

`Dom\{f\} = [0\,m,5\,m]`

`Ran\{f\} = [0\,m^(2), 10\,m^(2)]`
