Answer: domain: 0 ≤ x ≤ 8
Explanation:
Domain is an independent variable with a minimum and a maximum value. Or the starting point (value) to the end point (value)
The time taken by the ball is from 0 to 8 seconds
The domain of the function represented by the graph will be from the starting time of the ball to the end time. Therefore, In this case, domain will be
0 ≤ x ≤ 8
