Answer:
Option A. 0 < x < 3
Step-by-step explanation:
The question is as shown in the attached figure.
As shown :
The x-axis represents time in seconds.
The y-axis represents the height of the rock.
The height of the rock is representing a parabola function
- At time 0 the rock starts moving upward from 52 foot until it reaches 180 ft
- At time 3 seconds, the rock is at maximum height that is 180 foot.
- At time greater than 3 seconds the height of the rock decreases from 180 foot to 0 foot that is ground level.
So, The interval as observed from the graph where the height of rock is increasing is (0,3)
The answer is option A. 0 < x < 3
