<span> For this case we have the following function:
</span>
<span> When the food package is on the plane, we have that the height of the package is given by:
</span>
<span> Rewriting we have:
</span>
<span>
When, time passes, the height decreases.
When the time is 40 seconds (x = 40) the package reaches the ground and the height is 0.
Therefore, a reasonable domain for the function is:
0 ≤ x ≤ 40
Answer:
0 ≤ x ≤ 40
