Answer:
D. (0,5)
Step-by-step explanation:
We are given that,
The function f(x) represents the height of the object 'x' seconds after its launch in the air.
Also, the maximum height of the object is at 2 secs and the object hits the ground at 5 secs.
So, we get the following figure for the situation.
We have that,
<em>Domain of the function is represented by the time after the object is launched i.e. </em><em>the time when the object is in the air</em><em>.</em>
Since, the interval when the object is in the air is (0,5).
Hence, the domain of the given function should be (0,5).
